Plastic packaging is a commonly used type of packaging for most of the goods we come into contact with in daily life. I believe everyone is familiar with plastic packaging. The following are the specific classifications of plastic packaging and what aspects of life are different classifications applied to? What kind of plastic packaging is suitable for your product?

How are the common plastic packaging currently classified in the market? It can be easily distinguished from the following perspectives.

Firstly, if divided according to the packaging function required for the product, it can be divided into three-layer packaging in composite packaging bags and specialized packaging bags. The three-layer packaging in composite packaging bags is generally BOPP/PET/PE, BOPP/WMPET/PE, BOPP/PE, which can be used for most packaging materials, such as dried fruit packaging bags, seasoning packaging bags, candy packaging bags, vacuum roast duck packaging bags, etc. Most products can use this type of packaging material.

Special packaging bags are divided into the following types:

① For rice packaging bags, millet packaging bags, seed packaging bags, pet miscellaneous grain packaging bags, if the weight exceeds 2kg, it is recommended to use BOPA/PE or PET/BOPA/PE. BOPA has strong tensile strength, high oxygen resistance, and soft texture.

② High temperature steaming and boiling packaging bags: BOPA/RCPP is mostly used as the inner packaging bags for cooked food, including Soy egg packaging bags, roast duck inner packaging bags, etc. Because BOPA and RCPP have high temperature resistance, there is no problem in 121 ℃, 30 min high temperature, 131 ℃, 30 min high temperature.

③ Chemical product packaging bags: including pesticide packaging bags and chemical corrosive product packaging bags. PET/BOPA/AL/CPP is commonly used, but due to its use of anti-corrosion adhesive composite, CPP still has a certain degree of breathability. If corrosive liquids come into contact with the anti-corrosion adhesive through CPP after long-term use, it may cause delamination.

④ Washing products: laundry detergent packaging bags and laundry detergent self-supporting bag suction nozzle bags. The main packaging bags for laundry detergent are BOPP/milk white PE.

If classified by bag shape, the packaging bags currently in use in the market are also divided into many types according to different needs, such as self-supporting packaging bags, self-supporting zipper bags, three side sealed zipper bags, self-supporting suction nozzle bags, shaped bags, ordinary three side sealed, back sealed pillow shaped bags, five side sealed, medium sealed bags, etc. They each have their own characteristics and can better protect goods.

There are many considerations when choosing plastic packaging, and it is best to tailor it according to the needs of your product in order to achieve a better effect. This can not only enhance the attractiveness of the product's appearance, but also provide more comprehensive protection to prevent damage.
