Recently, a variety of paper packaging materials with moisture-proof and seepage-proof capabilities have been developed on the market, opening the door to paper packaging for liquid packaging.
The rapid development of China's packaging industry in recent years has brought great potential for various packaging materials. Taking paper packaging products as an example, this year's total output reached 8.35 million tons, and there is no sign of slowing down. It is a packaging material that competes with plastics. However, paper materials have been mainly used as solid packaging or outer packaging because of their poor moisture resistance and impermeability. Recently, a variety of paper packaging materials have been developed on the market to improve the above shortcomings and open up more uses for paper packaging.
Packaging wine and oil in paper
The latest application market for new paper packaging is alcohol packaging. For example, Japan is now popularizing the use of carton packaging instead of glass bottles as alcohol packaging. Western countries also use paper materials to package wine and fill it into Tetra Pak's aseptic brick cartons. The reason why the use of Tetra Bacterial bricks is mainly because the Tetra Pak has the advantages of safety, durability, non-breakable and explosion, and it is easy to carry and easy to open. In addition, one of its outstanding features is that the material is composed of 6 layers of composite materials, which enhances the sealability and enhances the anti-alcohol leakage and volatilization of the package. It also blocks direct sunlight and prevents deterioration.
Another insurmountable traditional paper packaging is oil packaging, because the oil molecules are extremely small and can easily seep through the paper packaging to the surface. Japan recently developed a boxed cooking oil-based composite carton that uses paper as the substrate and is made of 6 layers of aluminum-plastic composite. The structure is: PE/paper/PE/AL/PET/PE. The package made of the composite material is not only lightweight, safe, but also suitable for printing, so the packager can print a beautiful pattern on the box to improve the value of the product.
Reduce additives to improve reproducibility
New packaging to open up the application market, must meet the global trend - environmental protection requirements. Paper materials have always been considered environmentally friendly because they can be recycled into paper pulp. However, some paper packaging materials add other substances to increase the strength, which affects the recyclability. In Europe and America, a PLMEX food-specific wrapping paper is now popular. It does not contain fluorescent chemicals and chemicals that harm the human body. PLMEX made of paper is waterproof, oil-repellent, anti-sticky and heat-resistant, and can be washed and reused after use. It can be used up to 50 times.
BASF Chemicals Group has also developed a protective coating applied to the surface of packaging paper. This packaging paper coated with polymer dispersion is resistant to water, moisture, oil and grease. And without having to change the existing production process can be manufactured, does not affect the effect of recycling.
Liyang accept custom made different kind of paper packaging boxes, paper bag, gift box, jewelry box, mailer box, wine box, tea box , flower box and so on.
