Plastic thermal bags

Types of plastic thermal bags

Plastic thermal bags are made in diverse types. Each variation has been made to carry out a particular function.

• Insulated Grocery Bags

  Plastic thermal grocery bags work to keep food fresh. They do this by keeping up the needed temperature during grocery trips. Most variants have thick, insulated sides. This helps in resisting heat. Also, they have a zippered closure to give additional protection.

Materials & Durability of plastic thermal bags

Usually, plastic thermal bags are manufactured in various materials that are either durable or sensitive to changes in temperature. Below is a listing of some common materials used.

• Polypropylene (PP)

  Polypropylene is a common type of plastic used in the production of thermal bags. It is also quite versatile. This material is known for being resistant to moisture and heat. This gives plastic thermal bags durability and strength.

• Foamed Polyethylene (EPE)

  Users of plastic thermal bags often find EPE insulation bags. This sturdy and lightweight foam acts as a buffer against temperature changes. Moreover, EPE is shock-absorbent and makes it great for transporting fragile items.

• Linear Low-Density Polyethylene (LLDPE)

  In making thin-walled plastics, manufacturers often use LLDPE. This type of plastic is flexible. Therefore, it enables bags to be folded or stored easily in case one is not using them. In addition, LLDPE plastics are puncture-resistant. This makes them ideal for packaging sensitive goods.

• Aluminum Foil

  Some high-end thermal bags also have an aluminum foil lining. This material offers superb insulation properties. As a result, it forms a barrier against external temperatures and helps keep the contents either cold or hot for longer.

• Nylon

  Nylon is another tough material included in many thermal bags. It is equally resistant to wear and tear. This offers a longer lifespan for the bag. Moreover, nylon bags usually feature zipper closures. This increases their functionality.
