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.

In the end who owe the money？

In the end who owe the money？

   A lawyer's dog, running about unleashed, beelines for a butcher shop and steals a roast. Butcher goes to lawyer's office and asks, "If a dog running unleashed steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?" The lawyer answers, "Absolutely." "Then you owe me $8.50. Your dog was loose and stole a roast from me today." The lawyer, without a word, writes the butcher a check for $8.50. Several days later, the butcher opens the mail and finds an envelope from the lawyer: $250 due for a consultation.

Characteristics of plastic bags and Scope

Characteristics of plastic bags and Scope

Material:

Polyethylene 

Referred to as PE. Is the addition polymerization of ethylene polymer organic compound. Polyethylene is recognized as the world's best materials in contact with food. Non-toxic, tasteless, odorless, food packaging hygiene standards. Polyethylene film, light and transparent, with moisture, oxidation, acid, alkali, tightness in general, excellent sealing properties. Is the largest amount of plastic packaging and printing, the most important material. It is divided into two kinds of LDPE and HDPE.

LDPE

Low-density polyethylene, referred to LDPE, plastic packaging and printing industry for countries in the largest amount of variety. Specific gravity of 0.92 to 0.93, can float on water. Low crystallinity (60%), pressure 1000 ~ 3000kg /c㎡ bulk polymerization, it is also called high-pressure polyethylene. At 23 ° C, density of about 0.92. Suitable for food packaging, fiber products packaging, cosmetic packaging.

HDPE-- high-density polyethylene

High density polyethylene, referred HDPE, with low pressure polymerization, it is also called low-pressure polyethylene. Milky white, shiny surface is poor. Available blown film processing method and T-die extrusion process. Heat-resistant cooking, cold resistance, cold, moisture, air, good isolation performance, not easy to damage, high strength, easy opening.

Scope

PE scope of application is very plant, usually all items can be packaged using this material. Is currently on the market are more packaging materials, choose wide, generally the most commonly used material PE are: electronics, hardware, clothing (PE materials used by the electricity supplier as bags) courier bags, toys, food.

We should know what plastic bags we using

In dress items we will use plastic bags often, especially in the supermarket is inseparable from the use of plastic shopping bags. At present, we still have a great bag for dependence, bags provide convenience is good, but also generate a lot of negative issues. In the use of plastic bags on some relevant knowledge and caveats that we should need to understand the current and grasp.

Plastic bags with food products is the way that most people take for granted, a lot of selling breakfast restaurants or stalls, almost all packaged with a small vest pocket, the choice of this type of direct contact with food bags, we should know what the bag is in line with the level of food safety, so as to ease of use.Therefore, we should choose transparent odorless,non-toxic plastic bags, should not be loaded with colorful bags of food. Because the transparent bag is made of a new material, the use of recycled materials is variegated processing, quality different. Only the selection of qualified plastic bag in order to better protect our health. Followed by hot soups and other foods or food is best not to use plastic bags, such as hot milk, rice and so on.

When the use of plastic bags in our family, insists the idea of environmental protection is very important. All aspects of shopping bags are not used to throw away the casual, can leave it up, used to hold garbage or items containing a lot of life, so that will be able to reduce plastic waste in our favor environmental protection . Then to supermarkets and other shopping malls, we can readily bring the usual plastic bags stored, not only in this way can cost more affordable, but also in line with the promotion of environmental philosophy.

Plastic bags in a short time will remain a necessity in our lives, there is no better way of waste disposal bags before, we should choose better quality plastic products, many times the use of plastic bags, which is in line with current social development and create a good environment practices. To make better use of plastic bags, then the knowledge of these aspects are what we need to know.
