About insulated cooler bag?
An insulated cooler bag is a bag designed to keep its contents cool or refrigerated for extended periods of time. Bags are usually made of a durable material like nylon or polyester, with a layer of insulation between the outer and inner layers. Insulation helps maintain the temperature inside the bag, keeping items cool or cold.
Insulated cooler bags come in all shapes and sizes, from small lunch bags to large backpacks or wheeled coolers. They are commonly used for outdoor activities such as picnics, camping, hiking and beach trips, and for transporting perishable items such as groceries or medicines.
These bags usually close with zippers or other fasteners and may include additional features such as pockets, shoulder straps, and handles for easy portability. Some insulated cooler bags also feature built-in ice packs or compartments for storing ice cubes or gel packs to extend cooling even further.
The material of the thermal insulation ice pack?
Insulated ice packs are usually made of durable materials designed to withstand the wear and tear of outdoor activities. Materials used may vary by bag make and model, but here are some common materials:
Nylon: Nylon is a popular material for insulated ice packs because it is lightweight, durable, and waterproof. It’s also easy to clean, making it a great choice for outdoor activities.
Polyester: Polyester is another common material used in insulated cooler bags. It is strong, wear-resistant, and has good thermal insulation properties. It’s also fade and shrink resistant, making it a good choice for a bag that’s used frequently.
PVC: Polyvinyl chloride (PVC) is a synthetic plastic material commonly used to make the inner lining of insulated cooler bags. It is waterproof and has good insulating properties, making it an effective material for food and beverage refrigeration.
PEVA: Polyethylene Vinyl Acetate (PEVA) is a non-chlorinated vinyl material commonly used as a lining material for insulated cooler bags. It is an eco-friendly alternative to PVC and free from harmful chemicals like BPA.
Foam: Many insulated cooler bags have a layer of foam insulation between the outer and inner layers. The foam helps maintain the temperature inside the bag and is a lightweight and effective insulator. Hereby, as a trusted backpack manufacturer in China, we wholesale insulated ice packs all over the world. Remember, we always offer quality bags at lower prices and are waiting for your inquiry.
New technology for cold storage bag production?
Yes, manufacturers are using several new technologies and materials to produce more advanced insulated cooler bags. Here are some examples:
Airgel Insulation: Airgel is a highly porous material that is very effective at insulating heat transfer. Some manufacturers are using airgel insulation in their ice packs to create highly efficient and lightweight bags that can stay cold for extended periods of time.
Vacuum Insulation: Some manufacturers are using vacuum insulation to create cooler bags with better insulating properties. This technology involves removing air from the insulation, creating a vacuum that minimizes heat transfer and keeps the contents of the bag cooler for longer.
