Information About Cross-Linked Shrink Film

In current packaging, efficiency, durability, and product protection are top concerns. One material that has recently gained popularity for its performance benefits is cross-linked POF shrink film. These shrink films offer advantages for various applications across the packaging spectrum, ranging from industrial to food packaging.

In this article, we will define cross-linked shrink film, describe its production process, outline its applications, benefits, and explain why it is a leading packaging solution today.

What Is Cross-Linked Shrink Film?

Cross-linked POF shrink film is a variation of polyethylene shrink film that has been specially chemically or irradiated modified to create robust molecular links between polymer chains that increase the strength, elasticity, and thermal stability of the film to provide exceptional puncture, tear, and shrinkage consistency.  While typical shrink films often become brittle or simply break under extreme heat or tension, cross-linked films provide 99.99% uniform shrinkage and conform more snugly to the product being packaged for a secure and professional-looking finished product.

Types of Cross-Linked Shrink Film

There are different varieties of cross-linked films based on thickness, shrink ratio, and application:       

• Cast Cross-linked POF Shrink Film
• Blown Cross-linked Shrink Film
• Multi-layer cross-linked POF Shrink Film

How To Use Cross-Linked Shrink Film?

Using the proper equipment and procedure is crucial for altering the properties of cross-linked shrink film.

• Selecting the Film: Choose an appropriate thickness, shrink ratio, and type of film (cast or blown) based on the weight, shape, and type of package for your product.
• Heat: This shrink film requires you to control the heat source, so make it adjustable to maintain the appropriate temperature that will evenly shrink tightly to the product.
• Seal: You will want to make the proper seal, using a compatible sealing machine, which makes an airtight seal.
• Safety: Just use common sense and don’t overheat; excessive heat levels will ruin the film.

Applications of Cross-Linked Shrink Film

Cross-linked shrink film is versatile enough to serve various purposes:

• Industrial and Pallet Packaging: Cross-linked POF shrink film is used throughout the logistics and warehousing industries for pallet packages. Due to its strength, it protects loads against tearing and load shift when packing and shipping products.
• Food Packaging: Cross-linked films are one of the more important types of packaging in the food industry. Such items as lettuce, sausage, beef, and fish. Cross-linked shrink wrap tightly wraps and seals the product, providing durability in packaging, protection of the product, hygienic protection, and shelf life needs. 
• Printing and Branding: Cross-linked POF shrink film is also popular in packaging when high-quality printing is desired. Because of the enhancements of clarity and heat capabilities, the option for lighting for optimized brand appearance and visibility is resolved. 
• Packaging for Consumer Products: It is also widely utilized for consumer products, while conventional shrink films create tamper-evident packaging. Cross-linked shrink film has the advantages over conventional shrink films for consumer products by being able to utilize fluids, tabbed packages, odd shapes, and modular packaging.

Advantages Of Using Cross-Linked Shrink Film

There are several key advantages contributing to the growing demand for cross-linked film.

1. Maximum Strength and Durability

The cross-linking process creates strong molecular bonds to give great strength and resistance to rupturing, tearing, and stress for shipping and handling.

2. Uniform Shrinkage

Shrink films shrink evenly when heated, whereas standard shrink films shrink irregularly. This gives a snug, wrinkle-free package every time.

3. Enhanced Clarity and Appearance

Some high-quality cross-linked films yield superior clarity and gloss, making your product look appealing when displayed on retail shelves.

4. Resistance to Temperature Changes

Cross-linked shrink films can be structurally stable under high temperatures and function in cold storage and in heat and humidity.

5. Stability under Load

Cross-linked films are an excellent choice for palletized loads of goods. They provide premium containment of the load when in transit.

6. Sustainable Options

Many manufacturers are making recycled or partially biodegradable cross-linked shrink films as part of their effort to be sustainable.

Cross-Linked Shrink Film vs Standard Shrink Film

Understanding the differences between cross-linked and standard shrink films can help businesses make informed packaging decisions:
