Packaging films are primarily extruded from different grades of polyethylene resin, offering puncture resistance, high strength, and excellent waterproof properties. These films are widely utilized across various industries, including hardware, plastics, chemicals, building materials, food products, and pharmaceuticals.
In the packaging machine industry, different types of packaging films are suitable for various packing machines:
For VFFS (Vertical Form Fill Seal) Machines:
- Composite Films: These include combinations like PET composite PE, BOPP/CPP, PET/VMPET/PE, and BOPP/VMCPP. VFFS machines are versatile and can produce multiple bag types, making them ideal for a wide range of packaging needs across different product categories.
For HFFS (Horizontal Form Fill Seal) Flow Wrap Machines:
- Single-Layer Heat Sealing Films: Options such as BOPP or composite films like OPP composite PE, PET/PE, and BOPP/CPP are suitable for HFFS machines.
For Heat Shrink Wrapping Machines:
- PVC Films: These films are the preferred choice for heat shrink applications.
Comparison of Vertical and Horizontal Machines
Vertical Machines:
- Capable of producing various bag types, including back-side seal bags, three-side seals, four-side seals, gusset bags, quad seal bags, five-side bags, and bags with hanging holes. This flexibility makes vertical machines suitable for a broader range of products.
Horizontal Machines:
- Can produce back seal bags, gusset bags, four-side seals, and bags with hanging holes. While slightly more limited in bag type options compared to vertical machines, horizontal machines are still effective for many applications.
