Packaging bags There are many types, such as vacuum bags, aluminum foil bags, and aluminized bags. Below, we will introduce these types in detail.
1. Packaging bags - Vacuum bags:
The material structure of vacuum bags (also known as nylon bags) is usually PET / PA / PE Packaging bags with anti-static functions can be made according to customer requirements. This product has the characteristics of low air permeability, good vacuum effect, high transparency, good moisture resistance, high tensile strength, strong puncture resistance, easy heat sealing, good airtightness, and good aging resistance. It is mainly suitable for hardware, food, electronic components, etc. Products can also be printed with text, patterns, trademarks, etc., according to customer requirements, without infringing on the intellectual property rights of others, to help companies enhance their image.
2. Packaging bags - Aluminum foil packaging:
Aluminum foil bags, also known as pure aluminum bags, usually refer to aluminum-plastic composite vacuum packaging bags, suitable for moisture-proof, light-proof, and vacuum packaging of large-scale precision machinery, chemical raw materials, and pharmaceutical intermediates. It mainly adopts a four-layer structure and has good water and oxygen barrier functions. There are no restrictions; you can customize packaging bags of different specifications and styles, and they can be made into flat bags, three-dimensional bags, accordion bags, etc.
This bag can protect electrically sensitive components from potential electrostatic hazards. Their unique four-layer structure can form an induction effect and protect the contents of the bag from electrostatic fields. In addition, the inner layer is made of vinyl material, which can eliminate static electricity, thus preventing static electricity from being generated in the bag. This heat-sealable bag is semi-transparent, allowing the contents inside to be clearly identified from the outside.
3. Packaging bags - Aluminized bags:
Aluminized bag material structure VMPET / CPE (Fully aluminized film / Polyethylene film) has good heat sealing performance, good tear resistance, strong tensile strength, soft feel, the overall color is silver and opaque, high brightness, and the inside is invisible. It can be made into various styles: flat bags, self-sealing (compact bags / Zipper bags), envelopes, self-adhesive, one-piece, three-dimensional, etc.
