Information
In addition to accommodating and sealing the product, a packaging bag is more important to isolate the product from the outside world so as to protect the product.
 
In addition, the packaging material itself and the molecules of the product react with each other to cause the product to deteriorate, which has become a problem that the packaging bag manufacturer needs to solve. This article focuses on explaining how we solved this problem. Packaging bag manufacturers generally use PE material film in direct contact with the product. So, what is a PE material film?
 
PE, full name Polyethylene, is the simplest polymer organic compound and the most widely used polymer material in the world today. It is also the most widely used and most used film type in the packaging industry. PE protective film uses special polyethylene (PE) plastic film as the base material, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density.
 
The biggest advantage of PE protective film is that the protected product is not polluted, corroded, scratched during production, transportation, storage and use, and protects the original smooth and shiny surface, thereby improving the quality and market competitiveness of the product. .
 
According to the viscosity, it is mainly divided into: ultra-low-viscosity protective film, low-viscosity protective film, medium-low-viscosity protective film, medium-viscosity protective film, high-viscosity protective film, ultra-high-viscosity protective film
 
1. Ultra-low viscosity protective film (ie, slight bottom adhesion):
 
Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1500), base material (PE), peel strength (≤5g/cm), temperature resistance (60), elongation (> 400)
 
Uses: Easy to use, easy to stick and tear, no glue residue, suitable for organic plates, instruments, display screens, glass lenses, plastic lenses, etc.
 
2. Low-viscosity protective film
 
Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (10-20g/cm), temperature resistance (60), elongation ( >400)
 
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for steel mirror plates, titanium metal, smooth plastic plates, silk screens, nameplates, etc.
 
3. Medium and low viscosity protective film
 
Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (30-50g/cm), temperature resistance (60), elongation ( >400)
 
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc.
 
4. Medium adhesive protective film
 
Features: Thickness (≥0.05±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (60-80g/cm), temperature resistance (60), elongation (> 400)
 
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for surface protection of fine-grained frosted boards and general hard-to-stick materials.
 
5. High-viscosity protective film
 
Characteristics: Thickness (≥0.05±0.003), width (≤1.3), height (100-800), base material (PE), peel strength (80-100g/cm), temperature resistance (60), elongation (> 400)
 
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for fine grain frosted board, aluminum-plastic board, difficult-to-stick plastic board, etc.
 
6. Ultra-high viscosity protective film
 
Features: Thickness (≥0.04±0.003), width (≤1.3), height (100-800), base material (PE), peel strength (above 100g/cm), temperature resistance (60), elongation (>400) )
 
Uses: Very high viscosity, water-based acrylic is used as pressure-sensitive adhesive, which is convenient to use, easy to stick and tear, and no glue residue. It is suitable for hard-to-stick materials such as rough-grained aluminum plates.
