Crosslinked Polyolefin Shrink film is a high-performance packaging material made from polyolefin materials that have been treated with crosslinking to improve their heat shrink properties. This film offers excellent transparency and durability, and it is widely used in various packaging applications.
Excellent Transparency: Crosslinked Polyolefin Shrink film exhibits exceptional transparency, allowing for the clear display of the packaged items.
Durability: The film possesses high abrasion resistance and tear resistance, effectively protecting the packaged items from external hazards.
Heat Shrinkability: Due to the crosslinking treatment, the film shrinks when exposed to heat, tightly conforming to the packaged items and providing enhanced protection.
Environmental Friendliness: Crosslinked Polyolefin Shrink film is typically made from polyolefin materials, which have lower environmental impact and meet eco-friendly requirements.
Easy to Use: The film is easy to handle and package, and it can be easily applied using heat shrink equipment, improving production efficiency.
Crosslinking refers to the process of increasing the connection points between polymer chains through physical or chemical methods, forming a three-dimensional network structure. Crosslinked polymers exhibit the following characteristics compared to non-crosslinked polymers:
Increased Strength and Stiffness: Crosslinking enhances the strength and stiffness of polymers, making them more durable and resistant to deformation.
Improved Thermal Stability: Crosslinking improves the thermal stability of polymers, allowing them to maintain their properties in high-temperature environments.
Increased Shrinkability: Crosslinked polymers exhibit higher shrinkability, making them suitable for producing heat shrink films and tubes.
Enhanced Chemical Resistance: Crosslinked polymers have higher resistance to chemical corrosion, making them suitable for applications that require corrosion resist
Consumer Goods Packaging: This film is used for packaging a wide range of consumer goods, including personal care products, cosmetics, electronics, etc. It tightly wraps around the products, providing both protection and a visually appealing display.
Industrial Packaging: Crosslinked Polyolefin Shrink film finds extensive use in industrial packaging for protecting various products such as furniture, appliances, automotive components, etc. It offers excellent tear resistance and abrasion resistance, effectively safeguarding the products against external damage.
Bundle Packaging: This film is used to create bundle packaging, which facilitates convenient handling and stacking. It can wrap multiple products together, reducing the clutter in packaging.
Books and Magazine Packaging: Crosslinked Polyolefin Shrink film is commonly used for packaging books and magazines, providing protection and enhancing their presentation. It tightly wraps around the books, preventing dust and moisture intrusion while showcasing their appearance.
