Our market is like a food packaging bag. In behind, there are many techniques and hark works. And today, let’s find out what are the requirements of packaging technique pf food packaging bags.


Choose packaging materials with appropriate protective functions

Traditional packaging materials are mainly glass bottles, metal cans, paper boxes, cartons. Modern food packaging materials are mainly plastic, paper, composite materials (plastic/plastic, plastic/paper, plastic/aluminum, foil/paper/plastic and other types of multi-layer composite materials) and so on.


1. Composite materials composite materials are the most types of the most widely used soft packaging materials. At present, there are more than 30 kinds of plastics used in food packaging, and there are hundreds of multi-layer composite materials containing plastics. Composite materials generally use 2-6 layers, but special needs up to 10 layers or more. The plastic, paper or thin paper machine, aluminum foil and other base materials, scientific and reasonable composite or layer compatibility, can almost meet the requirements of different food packaging.


2. There are as many as 15 or 6 kinds of plastics used in food packaging in China, such as PE, PP, PS, PET, PA, PVDC, EVA, PVA, EVOH, PVC and ionic bond resin. Among them, PVA, EVOH, PVDC, PET, PA and PVDC, PP, PE and others are of high resistance to oxygen. Resistant to radiation, such as PS aromatic nylon; Low temperature resistance, such as PE, EVA, POET, PA, etc. Good oil resistance and mechanical properties such as ionic bond resin, PA, PET, that is, high temperature sterilization and low temperature resistance, such as PET, PA. Each kind of plastic monomer molecular structure is different, the degree of polymerization is different, the type and quantity of additives are different, the performance is also different, even if the same plastic different brand properties will have differences. Accordingly, must choose proper plastic according to the requirement or the combination of plastic and other material, the choice is improper may cause food quality to drop even lose edible value.


3. Paper and cardboard modern packaging mainly USES a variety of processing potato (cardboard), composite paper, laminated paper (cardboard), such as polymer materials processing paper, wax processing paper, oil processing paper, glass paper, parchment, aluminum paper, paper/aluminum foil laminated paper. In transport packaging, corrugated cardboard consumption, corrugated boxes, almost most of the pallet instead of wooden boxes. The honeycomb carton is the latest high strength cardboard container. In addition, there is a point should pay attention to, aluminized paper, aluminized plastic and paper/aluminum foil laminated materials, plastic/aluminum foil laminated materials inherent structure, properties, costs and other aspects of different, should be based on different protection requirements and cost requirements appropriate selection.


Adopt advanced packing technology

In order to prolong the shelf life, the use of continuous development of new packaging technology, active packaging, for example, anti-mold packaging, moisture-proof packaging, prevent mist, anti-static packaging, packaging, selective permeability antiskid packaging, packaging, etc., these new technologies, developed countries are widely used application is not common in our country, some methods is blank, the application of these advanced technology can obviously improve the protective function of packaging.


Choose and food processing technology matching packaging machinery and equipment

In order to meet the demand of food processing technology, a variety of new packaging equipment has been developed, such as vacuum packaging machine, vacuum inflatable packaging machine, thermal shrinkage packaging machine, bubble cover packaging machine, laminating packaging machine, sheet thermal forming equipment, liquid filling machine, forming/filling/sealing packaging machine, aseptic packaging complete sets of equipment. According to the choice of packaging materials and packaging methods, the selection or design of food processing technology, production capacity of packaging machinery, is the guarantee of successful packaging.


Packaging decoration design and brand awareness of packaging design

Packaging and decoration design should be in line with the consumer and exporting country consumer preferences and habits. The design is best coordinated with the interior. The label shall be in a prominent position and the written description shall meet the food requirements. The product description shall be true. Trademarks should be catchy, easy to understand, easy to spread, can play a wide role in publicity. The packaging design of famous brand commodity should be famous brand consciousness, the packaging of some products is changed easily, affect sale, for instance the old 6 vinegar of China have better reputation in Japan and southeast Asia, but the sale volume after changing a packaging decreases greatly, the reason is consumer has doubt to new packaging. Therefore, a product should be scientifically packaged, and not easily changed.


Packaging bag has become a part of our life, so small make up for you to interpret the requirements of food packaging technology, I hope we can have a clear understanding.
