Custom Cooler Bag Material

We use PVC (Polyvinyl Chloride) and TPU (thermoplastic polyurethane) materials to manufacture our outdoor products. These two fabrics are extremely durable, leak-proof, and of premium quality. PVC is a tough plastic that has excellent tensile strength and is resistant to weathering, abrasion, and corrosion. TPU, on the other hand, is highly elastic and can be easily molded. It is also resistant to oil and grease.

High Frequency Welding

Deficient welds can create leaks when the materials’ soldered parts are weak. Everich avoids this problem by utilizing high-frequency (HF) welding machines.

By using HF equipment, we ensure that our welds are strong and watertight. Our experienced team handles these machines, and as a result, our line of outdoor bags and gears are leak-proof. With the use of HF welding, you can drive brand loyalty because our products protect your customers’ belongings from heavy rains.

FAQS

FAQs About Wholesale Soft Cooler Bag

For your convenience, we have compiled the most frequently asked questions. Still, please feel free to contact us if you have any additional questions.

How Long Do Soft Coolers Stay Cold?

The duration a soft cooler stays cold depends on various factors, including the quality of insulation, the ambient temperature, the type and amount of ice packs or ice used, and how frequently the cooler is opened. Soft coolers are generally designed to keep contents cool for a shorter duration compared to hard-sided coolers, but they are still effective for more than 12 hours. Here are some general guidelines:

  1. Quality of Insulation: Higher-quality soft coolers often have better insulation, which can extend the time they keep items cold. Look for coolers with thick, well-insulated walls. Everich wholesale cooler bags are made of high-quality material and can keep cold and warm for more than 24 hours.
  2. Ambient Temperature: Warmer ambient temperatures will cause the ice to melt more quickly. If you are in a hot environment, the cooler will likely stay cold for a shorter duration compared to a cooler used in a cooler environment.
  3. Type of Ice Packs or Ice Used: The type and amount of ice packs or ice you use will affect the cooling duration. Reusable ice packs and high-quality gel packs tend to last longer than loose ice, and they won’t create a mess as they melt.
  4. Pre-chilling: Pre-chilling the cooler and its contents before use can extend the cooling time. If possible, store the cooler in a freezer overnight before filling it.
  5. Frequency of Opening: Each time you open the cooler, warm air enters, and cold air escapes. Limiting the number of times you open the cooler can help maintain a colder temperature for a longer period.
  6. Proper Sealing: Ensure that the cooler is sealed properly to prevent air exchange, which can impact its ability to retain cold temperatures.

As a general guideline, a well-insulated soft cooler can keep items cold for approximately 12 to 24 hours. However, this can vary based on the factors mentioned above. It’s always a good idea to check the manufacturer’s recommendations for your specific soft cooler model, as they may provide more precise information on expected cooling durations.

How To Use A Cooler Bag?

As a leading soft cooler factory in China, here’s a step-by-step guide on how to use a cool bag effectively we concluded:
  1. Preparation: Before using the cool bag, make sure it is clean and free from any lingering odors. If needed, wipe it down with a mild soapy solution and rinse it thoroughly. Allow it to air dry completely.
  2. Chill the Bag: For optimal performance, pre-chill the cool bag by placing it in a freezer for a few hours before you plan to use it. This helps to enhance its insulating capabilities.
  3. Select the Right Ice Packs: Choose the appropriate ice packs or ice substitutes for your specific needs. Gel packs, ice packs, or frozen water bottles are common options. Avoid using loose ice, as it can create a mess as it melts.
  4. Pack Items Properly: Pack your items in the cool bag, placing the coldest items at the bottom. This helps in maintaining a consistent temperature throughout the bag.
  5. Use Insulation: Consider using additional insulation layers if you have them. Wrapping items in towels or using extra padding can help maintain the temperature inside the cool bag for a more extended period.
  6. Seal the Bag Tightly: Ensure that the cool bag is sealed tightly to prevent warm air from entering and cold air from escaping. Most cool bags come with zippers or Velcro closures. Double-check the seal to avoid leaks.
  7. Avoid Opening Frequently: Minimize the number of times you open the cool bag, as each opening allows warm air to enter and compromises the internal temperature.
  8. Keep it in the Shade: Whenever possible, keep the cool bag in a shaded area or covered with a towel or blanket. Direct sunlight can increase the temperature inside the bag.
  9. Replenish Ice Packs: If your outing lasts for an extended period, consider bringing extra ice packs or frozen items to replace melted ones and ensure that the contents remain cool.
  10. Clean and Dry After Use: After using the cool bag, empty it, clean it if necessary, and allow it to air dry before storing it. This helps prevent the growth of bacteria and mold.
By following these steps, you can maximize the effectiveness of your cool bag and keep your food and drinks cool and fresh for a longer time.

Can You Put Ice In Cooler Bags?

Yes, you can put ice in cooler bags. In fact, using ice or ice packs is a common and effective way to keep the contents of your cooler bag cool. Moreover, it’s often more convenient to use reusable ice packs rather than loose ice. This helps prevent water leakage and keeps your items dry. While you can use loose ice, it’s generally less practical as it can create a mess as it melts.

Here are a few tips when using ice in a cooler bag:

  1. Pre-ce Cooler Bag: For better cooling performance, pre-chill the cooler bag in a freezer before loading it with ice and your items.
  2. Layering: Place the ice packs or loose ice at the bottom of the cooler bag. This helps cool the entire contents evenly.
  3. Seal the Bag Properly: Make sure the cooler bag is sealed tightly to prevent warm air from entering and cold air from escaping. Proper sealing helps maintain the internal temperature for a longer period.
  4. Monitor and Replace Ice: Keep an eye on the ice inside the cooler bag. As it melts, consider replacing it with fresh ice packs to maintain a consistently cool temperature.
  5. Avoid Overfilling: Leave some space in the cooler bag for air circulation. Overfilling can reduce the effectiveness of the cooling process.
  6. Use Insulation: If possible, use additional insulation layers such as towels or blankets to further enhance the cooler bag’s performance.

Remember to follow the cooler bag manufacturer’s guidelines for your specific cooler bag, as some bags may have unique features or recommendations for optimal use.

How to keep a cooler bag cold? | Tote Bag Academy

"Updated: 6/11/"

You can do a few things before you get ready to fill your ice cooler bag for your next camping trip or day at the park to guarantee that your ice, and ultimately, your food, stays as cold as possible for as long as possible.

When using a cool bag, one of the most difficult problems is preventing the ice from melting too rapidly. This may cause your food to become mushy and unhealthy, while also causing your drinks to warm up. And what could possibly be worse than lukewarm beer? To extend the time your cooling capacity lasts, you only need a few common home goods and some ingenious packaging tricks.


How Does Cooler Bags Work?

Most lunch bags that are insulated come with many layers of insulation. In most cases, they consist of three layers: an outside layer, an inner layer, and a middle layer that provides insulation. The center layer is of the utmost significance since, in the absence of this component, a lunch bag would be no different than a regular lunch box.

To prevent energy loss, thermoses and insulated lunch boxes rely on a vacuum created between the outer layer and the inner layer of the container. On the other hand, insulated lunch bags use a dense foam core layer to keep food and drinks at the appropriate temperature. The insulation provided by the foam is significantly improved by increasing its thickness and density.

If you want to learn more, please visit our website Insulated Cooler Tote Bags Wholesale.

The foam layer stops heat from leaking to the outer layer and also inhibits the cold or heat from the environment from penetrating the bag and reaching its contents. It is possible that you may observe that the exterior of insulated lunch bags does not heat up when loaded with warm goods. This is because the heat is prevented from dispersing in the surroundings, which leads to this observation. (The outside layer of the majority of lunch bags is often constructed out of non-woven fabric, vinyl, or thick cloth.)

Many insulated lunch bags come with an inside layer or lining that is composed of foil, thick vinyl, or plastic that is watertight and heat-reflecting. This serves as an additional layer of protection for the contents of the lunch bag.

While cooler bags are very convenient, they’re not exactly capable of doing magic. Depending on the model you have, hot food should remain warm for about two to four hours, while cold food will keep its cool for about three to six hours at best. This primarily depends on the materials used during production.

Things to Know Before Using

Many cooler bag users end up with complaints after encountering several problems with their bag. However, most of the problems they pose refer to themselves, the users, instead of the bags! This is because cooler bags have particular usage methods, and if these are not applied properly, it is quite likely that the bag would not serve its purpose. What are some common mistakes to avoid when trying to keep cooler bags cold?

Well, note that when trying to keep your cooler bag cold, a few common slip-ups can make a big difference. One of the biggest mistakes is packing warm or room-temperature items—this warms up the whole bag quickly, so always pre-chill your food and drinks. Another is using too few ice packs or not placing them strategically; it's best to have some at the bottom and on top of your items to surround them with cold. Leaving the bag open too long while packing or rummaging through it lets cold air escape, so try to keep it zipped up as much as possible. Also, putting your cooler bag in direct sunlight can heat it up fast, so always find a shady spot. And lastly, skipping the pre-chill step for the bag itself means you’re starting off at a disadvantage. A little planning goes a long way in keeping everything fresh and chilled! Now let us have a closer look to these factors.


Avoid Direct Sunlight

If at all possible, store your luggage where it will be protected from direct sunshine and shade. However, if you can maintain the bag at a colder temperature for a longer period, the ice inside will be usable for longer. This obviously depends on where you are. Be sure to keep the zip-lock tight to prevent warm air from escaping and allow cold air to enter. Because both our insulated cooler backpacks and cool waterproof bags are outfitted with ThermalLock insulation, this is an essential step in maximizing the usefulness of your cool bag and figuring out how to keep it cold.

Put these best practices for maintaining the temperature of a cooler bag into practice. Your favorite foods and beverages should be able to maintain their high level of freshness for a significantly longer period of time. On our website, you can discover instructions that will help you select the Red Original waterproof cool bag that is most suited for your needs.


Keep it Organized

Warm air will enter your cooler whenever you open and close the lid, hastening the process by which the ice melts. You may reduce the length of time the lid is left open by organizing the contents of your cooler such that the goods you will require most frequently are located on one side. If you want to find what you need without wasting time digging around, you should organize your cooler so that each opening is as productive as possible.

Prepare the Interior 

Before using your cooler bag, it is better to prepare its interior in order to lengthen the duration for which you want to keep it. Therefore, many users ask, how can I effectively pre-chill my cooler bag before packing? To effectively pre-chill your cooler bag, try popping a few ice packs or frozen water bottles inside it the night before you plan to use it. This helps lower the internal temperature so your food or drinks stay colder for longer. If you're short on time, even just 30–60 minutes with ice packs can make a noticeable difference. Also, keep the bag zipped or closed tight while pre-chilling so the cool air doesn’t escape. For best results, chill your food and drinks beforehand so you're not introducing warm items into the bag. When packing, use a layering method with ice packs on the bottom and top of your items to maximize cold retention. Always keep the bag out of direct sunlight, as shade helps maintain a lower internal temperature.


Use Big Ice Blocks

Since we just mentioned keeping it organized is helpful to keep cool bags cold for a while, here is another tip for the interior. Compared to tiny ice cubes, larger ice blocks have a lesser amount of surface area exposed to the warmer air outside, which is one of the benefits of employing larger ice blocks. Because of this, bigger ice blocks melt at a far slower pace than ice that has been cubed. You may simply build your own ice blocks at home by utilizing a milk carton that has been cleaned and is empty as a mold. After making sure there is enough area for the water to expand, fill the carton with water and then freeze it. After the contents have been frozen, remove the carton and put it in your refrigerator. Despite their size, they have a far longer lifespan and perform their functions more efficiently.


The ratio of Ice to Contents

When it comes to keeping your cooler bag cold, having more ice means the ice will stay frozen for longer. Because of this, if you want the contents of your cool bag to remain cold for a longer period of time, you should choose a cooler bag with a greater capacity so that you may pack it with more ice. If you want to have ice for your beverages, we recommend using twice as much ice as the amount of liquid in the container, but if you just want to keep the food at your picnic cold throughout the day, a few cool blocks will do the trick.


Additional Aluminum Foil Layer

Keeping the heat out is the single most critical thing you can do to keep the contents in your cooler bag cold. Aluminium foil, which helps reflect heat and light that would otherwise quickly melt your ice, may be used to line the interior of your cooler, which is an excellent approach to accomplish this goal. You might also use thermal bubble wrap to assist in preventing hot air from escaping and allowing cool air to enter. You may also try placing a layer on top of your cool bag to assist it reflect any other UV rays that may be present.

Pre-Chill Your Cooler Bag

If you want your ice to stay colder for a longer period of time, one of the finest things you can do is to chill your cooler before you put fresh ice in it. You may do this by placing ice in the cooler bag a few hours or even a day before the event, and then letting it cold to the maximum extent feasible. When you are ready to get going, doing this will assist the new ice last for a longer period of time. 

You may also freeze water bottles or non-carbonated drinks to use as extra cooling things that will assist in keeping your ice for longer. This will keep your ice from melting as quickly. In addition to this, before you put anything in the cool bag, ensure that everything you intend to put in it has already been adequately cooled. Instead of putting warm drinks or food at room temperature into the cooler, try freezing or chilling as much as you can beforehand.


Wrap a Wet Towel Around Your Cooler Bag

Wrap the cooler with a damp towel of a light color, and keep it tucked away in the shade as much as possible. The water will start to evaporate off the towel as soon as the breeze blows over it. The towel will get chillier as the water evaporates and transforms into vapor. This will assist in maintaining a lower temperature in the cooler bags allowing the ice to stay frozen even longer.


Camp Hack: Burry Your Cooler Bag

If you are going to be away from home for several days, you might want to consider burying your cool bag in the ground. Even if it might not make sense at first, the fact that the soil is chilly will make it possible to keep the same temperature for a longer. Make sure that you only bury it three-quarters of the way, and pick a location with some shade.


Drain the Melted Ice Water

Despite what you would believe, storing melted water in the refrigerator is not the most logical thing to do. The presence of water makes it far more probable that heat will be transferred by convection, which will cause the ice to melt more quickly. Your ice will melt gradually if you drain the water as it gathers on the surface of the ice.
