What are the materials of isolation bags?

1、Polyethylene (PE):

。Features: moisture-proof, waterproof, oil-proof, and dust-proof.
。Application: Widely used in food, medicine, chemical and other industries.

2、Polypropylene (PP):

。Features: high strength, tensile strength, waterproof, and moisture-proof.
。Application: Commonly used in chemical, mining, agricultural products and other industries, and also used as raw materials for making coated non-woven bags. The chemical structure of polypropylene bags is not strong, the molecular chain is easy to break, and it can be effectively degraded, which is an environmentally friendly material.

3、Nylon (NY):

。Features: high strength, waterproof, moisture-proof, and anti-oxidation.
。Application: Suitable for packaging chemical products, food and other items, and also used to make vacuum bag films. Due to its excellent temperature resistance and high strength, it is widely used in the molding and curing process of epoxy and bisma-based composite materials.

4、Polyester (PET):

。Features: high strength, waterproof, moisture-proof, and anti-oxidation.
。Application: Commonly used for packaging chemical, pharmaceutical, grain and other items, and also used to make breathable felt.

5、Non-woven fabrics.

。Features: moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low price, and recyclable.
。Application: Suitable for making coated non-woven bags, which are used for the production of disposable medical sheets, bed sheets, surgical gowns, isolation suits, protective clothing, shoe covers and other sanitary protection products.

6、Isolation film:

。Material: polyester, ETFE, FEP, polyimide, etc.
。Features: transparent, high temperature resistant, temperature resistance ranging from 120℃ to 400℃.
。Application: used for isolation or demolding in the vacuum bagging process of composite materials. ETFE and FEP isolation films are mainly used in the molding process of aerospace composite materials.

7、Paper

。Features: degradable, environmentally friendly, with certain strength and toughness.。Application: used to make fruit bags to prevent fruits from being attacked by birds, pests and diseases, and damage from wind, rain and sunlight.
。In addition, there are some special materials for isolation bags, such as aluminum foil composite bags, which have excellent barrier properties and are often used for packaging with high barrier requirements; and materials containing special additives, such as anti-static materials and UV-proof materials, to meet specific application requirements.

When choosing the material of the isolation bag, comprehensive consideration should be given to factors such as the specific application scenario, item characteristics, environmental conditions, and cost budget.
