A compilation of the most commonly used types of heat shrink film today.

What is shrink wrap?

Shrink wrap, also known as heat shrink film, is a type of packaging material made from polymer plastic film. Its outstanding characteristic is its ability to shrink when exposed to high temperatures, tightly wrapping around the product being packaged.

Characteristics of shrink wrap:

Stretchability: Shrink film can shrink to 2-3 times its original size when heated, allowing it to tightly wrap around products of various shapes and sizes.
High mechanical strength: Shrink film has good tensile, tearing, and impact resistance, protecting products from external influences.
Waterproof and airtight: Shrink film creates an effective barrier, preventing dust, moisture, bacteria, and mold from penetrating the product.
High aesthetic appeal: Shrink wrap has a beautiful glossy finish, enhancing the product's aesthetics and attracting consumer attention.
Environmentally friendly: Some types of shrink wrap are made from recycled, biodegradable materials, contributing to environmental protection.

Classification of shrink wrap:

PE (Polyethylene) shrink film: This is the most common type of shrink film, made from PE plastic. It is inexpensive, has high mechanical strength, and is waterproof. PE shrink film is commonly used for packaging food, beverages, pharmaceuticals, etc.
