32-Can 840D Cooler Bag TPU Leakproof Waterproof Insulated Bucket Style for Food Wine CBG032B802

The sample period is usually 7-10 days. For mass production, after the deposit payment and sample confirmation, it usually takes 30-45 days (depending on the order size and the complexity of customization).

• Direct purchase/simple customization: from as few as 10 to 100.
• Deep customization: Usually ranging from 500 to 1000 units (depending on the material procurement requirements).

We are very accommodating to start-up brands and are happy to provide specific solutions upon consultation.

Yes, we will provide a pre-production sample for you to test the durability and insulation properties of the material. We won’t start mass production until you give us a written confirmation.

• Simple customization (Logo Branding/color alteration): Add your Logo (screen printing, heat transfer printing or rubber label) to our existing styles or change the color combination. This is suitable for customers who seek rapid delivery and low minimum order quantities(MOQ).
• Full customization (Full OEM/ODM): From capacities, dimensions, shapes, specific functions (such as bottle openers, air valves, bungee cord nets, reflective stripes, air valves, solar panels, LED panels, etc.), all the way to exclusive color schemes and special materials development. We will provide you with 3D renderings and sample prototypes for confirmation.

Unlike hard coolers, dry ice cannot be used inside the soft cooler bags. Extremely low temperatures can damage the fabric and insulation materials, and some cooler bag models do not come with valves, which poses safety risks. We recommend that you use regular ice or ice packs.

Most of the cooler bags are waterproof both inside and outside. Therefore, after use, rinse off the residues with clean water, wipe off the stains gently with a towel and mild detergent, and then dry them. Please avoid using the washing machine or dishwasher to prevent the high temperature or tearing from damaging the bag material.

Yes. We have adopted high-frequency welding (RF Welding)/ultrasonic fusion welding technology instead of traditional sewing to ensure that the bottom and seams are completely seamless. Combined with an airtight and waterproof zipper, even if the bag tips over, the liquid contained inside will not leak.

Although the insulation effect of soft cooler bags usually cannot reach the upper limit of hard coolers (7-10 days), they are lighter in weight and easier to carry, and their application scope far exceeds your imagination:

• Outdoor leisure: Camping, picnics, beach parties, fishing, hiking.
• Urban life: Shopping for fresh produce or chilled dairy products at the supermarket, preparing meals for daily consumption (with insulation for heat preservation or cold preservation), and storing breast milk.
• Specialty fields: Food delivery services, “the last mile” cold chain logistics for fresh produce.
• Business application: Brand collaboration gifts, corporate anniversary presents, sponsorship items for outdoor sports events.

We mainly use PVC, high-density TPU or 600D/1600D Oxford fabric as the outer shell, and food-grade PEVA or TPU as the lining inside. The middle layer is filled with NBR, EPE or HDPE closed-cell foam. According to laboratory tests, in a room temperature environment, our high-performance cooler bag can keep the ice cubes from melting for 24 to 72 hours. All the materials we use have passed BPA-Free, REACH and RoHS certifications, ensuring safety when in contact with food/beverage and free of any unpleasant smells/odors.

Our production process combines traditional sewing with modern high-frequency welding technology to ensure the durability of each bag:

• Material selection: According to the design drawings, we use precision CNC machines to cut large pieces of raw materials such as TPU, Oxford fabric, and insulation foam.
• Material lamination: The outer layer (polyester/nylon/TPU), the middle layer (PE closed-cell foam/foam material), and the inner layer (TPU/PEVA/PVC) are laminated into a single composite fabric using high-frequency radio frequency (RF) welding technology or ultrasonic fusion welding through molecular friction to generate heat.
• Cutting: Use laser or die-cutting machines to precisely cut the sheet materials according to the design template.
• Logo printing: According to customer requirements, silk screen printing, heat transfer printing, or embroidery is carried out on the sheet materials.
• Welding: For TPU/PVC materials, different parts are fused/welded together to form a completely waterproof, needle-free, and tear-resistant bag.
• Accessory attachment: Sewing or welding zippers (conventional zippers or airtight waterproof zippers), handles, shoulder straps and multi-functional hooks, etc.
• Pressure test and QC: Test the airtightness, leak-proof performance(especially of the zipper and the bag bottom) and insulation duration of the cooler bag to ensure absolute reliability.

Soft shell cooler bag is a portable soft container with insulation function. Unlike the traditional hard-sieded plastic cooler boxes, it is made of flexible and relatively soft composite materials.

Hard coolers are usually made of three layers of materials – the inner and outer layers are sturdy and waterproof food-grade PP/PE, and the middle insulation layer is usually PU foam. Similar to hard coolers, soft coolers are also usually composed of three layers. The outer layer is a wear-resistant and waterproof fabric, such as Oxford cloth/Nylon coated TPU/PVC; the middle layer is a high-density insulation foam, such as EPE/NBR/HDPE; and the inner layer is a food-grade waterproof lining, such as PEVA or TPU/PVC.

Its working principle is the same as that of a hard cooler. Both effectively prevent heat exchange between the inside and outside through the middle insulation layer (high-density foam). When used in combination with ice packs or ice cubes, it can maintain an internal low temperature for the entire day or even for 2-3 days.
