Introduction of Anti-rust three-dimensional bag products

Black stretch film is a special function of industrial packaging material, its main characteristics, application scenarios and selection points are as follows:

1. Core characteristics and functions of black winding film

Black winding film material and process

It is made of polyethylene (PE) as the base material and black masterbatch is added to make it with high tensile strength, self-adhesion and light shading.
Surface viscosity is only present between the film layers and does not remain on the packaged material.

Function advantages of Black stretch film

Light protection: effectively block light, protect photosensitive items (such as food, medicine, photosensitive equipment).
Security and anti-peep: the black opaque design hides the contents, protecting privacy and valuables.
Dustproof and moisture-proof: tightly wrapped to form a physical barrier, blocking dust and water vapor.
Wear and puncture resistant: enhance the surface protection of goods, reduce transportation wear.

Application scenarios of Black stretch film

Black stretch film industry

Building materials, chemical raw materials, precision instruments: moisture-proof, dustproof and light protection.
Pallet reinforcement: increase the friction of goods to prevent collapse during transportation.

Black stretch film sensitive goods

Electronic products, drugs and food: use light shielding to delay deterioration.
Valuable items: anti-theft packaging (such as works of art, confidential documents).

Special requirements for Black stretch film

Temporary waterproof layer of construction, wear-resistant coating for sports equipment (such as ski suits).

Fourth, the key points of black winding film selection

Thickness selection: 20-50μm (20μm for routine dustproof, 50μm for heavy goods).
Tensile strength: machine film needs to be> 300% tensile rate 10.

Precautions for storing Black stretch film

Avoid high temperature environment (>25℃) to prevent the migration of PIB adhesive resulting in decreased viscosity.
Store in a cool and dry place to avoid deformation of the film roll under pressure.
