Shrink Film Blowing Machine

The shrink film blowing machine is the primary equipment used to produce shrink film. This versatile machine enables the creation of films that cater to a wide range of packaging needs across various industries. Depending on the materials and characteristics of the films produced, these machines are suitable for high-end film packaging, plastic bag films, protective films, and more.  

Shrink films produced by film blowing machines exhibit excellent barrier properties, making them ideal for both light and heavy packaging. They are used to preserve and protect products due to their fresh-keeping, moisture-proof, frost-proof, oxygen-proof, and oil-resistant qualities. Applications include packaging for fresh fruits, meat products, pickles, fresh milk, liquid beverages, and medical supplies, among others.

The Features of Shrink Film Blowing Machine

1. Material Versatility

   The AB two-layer co-extrusion blown film machine is suitable for low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), ensuring adaptability for diverse applications such as agricultural films, courier bag films, and two-color films.

2. Durable Forced Feeding Main Machine 

   The ldpe blown film machine equipped with dual-alloy forced-feeding screws, the machine offers exceptional hardness and wear resistance, capable of plasticizing a significant amount of material under high speed and pressure. These screws have a service life 3-5 times longer than standard screws.  

3. Optimized Cone Stacking Mold

   The machine employs a two-layer cone stacking mold, designed using thermofluidics and 3D simulation software. High-level polishing and coating ensure self-cleaning during high-speed operations, reducing waste and downtime during maintenance.

4. Advanced Automation Module 

   Features centralized feeding, batching, weight control, and automatic central winding, all managed via an integrated touch screen interface. This enhances productivity and simplifies operations. 

5. Technical Specifications:

   • Film Width: 800mm-1500mm
   • Film Thickness: 0.01-0.14mm
   • Maximum Output: 80kg/h-160kg/h
   • Die Head Type: Two layers Rotary Die Head
   • Air Ring: Double lips air ring

Materials Used in Shrink Film Blowing Machines

Although film blowing machines can use a wide variety of materials, LDPE is the most commonly used material for producing shrink films due to its exceptional qualities. LDPE shrink films are highly valued for their high tensile strength, elongation, and transparency, making them ideal for packaging and securing items during transportation. They are extensively used in industries such as foreign trade, food packaging, construction materials, and pharmaceuticals.

The versatility of film blowing machines allows them to also produce films from materials such as PP, which are suitable for supermarket shopping bags and mushroom bags that require higher hardness but lower stretchability. High-pressure PE films cater to fresh-keeping bags, while recycled materials are used to create garbage bags. These varied applications highlight the adaptability of film blowing machines to different raw materials and their corresponding industrial uses. 

What is Shrink Film?

 

In addition, the packaging method of shrink film has the characteristics of unitization, primary protection, compression fixation and cost saving, which can effectively protect the product and prevent dislocation and movement during transportation, while reducing packaging costs and improving packaging efficiency.  LDPE shrink film, in addition to its applications in the packaging industry, is also frequently used in the transportation sector to ensure items remain securely in place during transit, providing added stability and protection. 

• PVC Heat Shrink Film

  PVC heat shrink film is a film material made by mixing ethylene-based PVC resin with a variety of auxiliary materials and then blowing it twice. It has the characteristics of good transparency, easy shrinkage, high strength and adjustable shrinkage rate according to user needs. It is widely used in the packaging of goods such as wine, food, sports goods and sterilized tableware.

• LDPE Shrink Film 

  LDPE shrink film, that is, polyethylene shrink film, is an industrial film product with high tensile strength, large elongation, good self-adhesion and transparency. It is mainly used for manual or machine wrapping film, and is widely used in the centralized packaging of various goods, such as foreign trade export, papermaking, hardware, plastic chemicals, building materials, food and medicine and other industries.
