OPP bag you know how much?

OPP bag you know how much?

OPP bag is a stretch of polypropylene, is a form of plastic, in fact, a plastic bag, its features are: easy to burn, the flame: The melting dripping down on the yellow and blue, less smoke from the fire continues to burn.

OPP [1] (Oriented polypropylene): oriented polypropylene (film), a polypropylene and biaxially oriented polypropylene (BOPP)
O (Oriented): mainly refers to the production process
PP [2] (polypropylene):polypropylene. Can be used for general structural parts, corrosion-resistant chemical equipment parts, electric heat insulation.

OPP bag:
With high transparency, more brittle and other features, by the OPP after chip sealing and fold the sides of the tongue in the opening sticky adhesive seal products are loaded using tear seal to protect the surface of the skin after the tongue can be folded and cement, easy to use, elegant, widely used in clothing, food, printing, stationery, cosmetics, paper and other industries. Also based on customer need to print a variety of patterns and playing butterfly hole Aircraft hole.

OPP film has distinct advantages:
A good sealing. Experimental data show that the new sealing OPP film is its traditional film more than doubled, making it the product of moisture, fresh stronger, longer lasting;
Second, strong security. The new membrane synthesis techniques used and the special printing technology with high technology content, only Germany and Japan, the two master the technology, the production of counterfeit almost impossible for the commodity to provide a strong security guarantee;
Third, the new OPP film material used for biodegradable materials, it is in full compliance with international environmental protection standards.
The new OPP film has been in the tobacco Blair, currently the number of large companies have begun to use.

Edit this paragraph OPP main product lines
OPP Tape: polypropylene film to the substrate, with high tensile strength, light weight, non-toxic, odorless, environmentally wide, range, etc.
OPP bottle: light weight, low cost, improve transparency, heat resistance, suitable for hot filling. In recent years, biaxially oriented polypropylene (OPP) transparent bottle became the election on behalf of PET bottles.

Food Vacuum Packaging Technology Overview

Food Vacuum Packaging Technology Overview

Vacuum packaging, simple to say that the most important role is that of oxygen, in order to help prevent food spoilage.

The principle is very simple vacuum-packed. The main reason is the deterioration of food mold rot caused by microbial activity, and microorganisms (such as molds and yeasts) need oxygen to survive, this principle is the use of vacuum packaging, the packaging bag and food cells deprived of oxygen, microorganisms lose "living environment." At the same time, it also prevents the oxidation of food due to leaving the food taste, bad, in order to achieve longer food storage and preservation effect.

Food vacuum packaging materials and composite types
Performance food vacuum packaging materials, direct impact on the change in food shelf life and taste. During vacuum packaging, packaging materials, a good choice is the key to the success of the packaging.
