Disposable paper cups are currently more frequently used daily necessities in daily life. In order to enhance the safety of disposable paper cups, Shanghai Yifu Packaging Group's PLA coated paper and environmentally friendly non-toxic paper container project.
Natural corn as raw material
At present, the disposable paper cups on the market are mainly divided into three types: one is made of white cardboard, which is mainly used to hold dry things, and cannot hold water and oil; the second is a wax-coated paper cup. The wax is soaked, so it is more waterproof and thicker, but as long as the temperature of the water in the cup exceeds 40 ℃, the wax will melt, and the wax contains carcinogens polycyclic aromatic hydrocarbons; the third is the paper-plastic cup commonly used by people now, The outside is a layer of paper, and the inside is a layer of coated paper. The quality of the coated paper determines whether the paper cup will produce harmful substances during use
An industry source told reporters that the raw materials of disposable paper cups are prevalent in the industry at a relatively low price, but the disadvantage of this kind of pulp is that it is easily deformed when cold or hot, and the seams are easy to crack. Most domestic paper cup manufacturers use cane pulp, which is about 1/3 cheaper than wood pulp, but the large-volume paper cups produced by cane pulp are not as strong as wood pulp paper cups. When they contain some higher temperature liquids, It is easy to rupture and cause safety hazards. At the same time, the sugarcane pulp is dark in color, and some undesirable manufacturers may beautify by using bleach or fluorescent powder in order to achieve the aesthetic effect of the product.
According to industry sources, PLA coated paper is made of 100% corn plastic PLA raw material, without any additives, and 100% PLA raw material is coated on the paper.
The reporter learned that the traditional paper composite materials are made of paper as the substrate and compounded with plastic coatings such as LDPE and PET. Due to the non-degradable nature of plastics such as PE and PET, such packaging materials cannot be completely satisfied. Environmental protection in the sense, and the development of fully biodegradable material PLA and its coated paper technology have completely solved this worldwide problem.
PLA coated paper (biodegradable coated paper) is itself an environmentally friendly and healthy product that is completely decomposable and compostable.
Polylactic acid (PLA) is a new type of biodegradable environmentally friendly material, made from starch raw materials proposed by renewable plant resources (such as corn). The starch raw material obtains glucose through saccharification, and then fermentes glucose and certain strains to produce high-purity lactic acid, and then synthesizes polylactic acid of a certain molecular weight through chemical synthesis. It has biodegradable and compostable thermoplastic materials, which use plants as the main source of raw materials; 100% completely biodegradable materials that are extracted, fermented and polymerized, can be completely eliminated by microorganisms in nature in a composting environment Degraded into carbon dioxide and water needed for plant growth. It has good biodegradability and does not pollute the environment, which is very beneficial to protect the environment and is recognized as an environmentally friendly material.
Compared with traditional PE coated paper products, PLA coated paper products can be recycled after use. The special and diversified recycling methods of renewable resources greatly reduce the burden of natural resources and the environment, which is in line with life. The endless green cycle guidelines.
PLA coated paper, pla can be degraded. Manufacturers with higher requirements use PLA. The price of PLA is high, and the relative cost performance will be higher. In the long run, it will be more developable and easier to gain consumer welcome. , In response to the concept of safety, environmental protection and sustainable development of ***, the future market must belong to PLA coated paper (biodegradable coated paper)
Shanghai Yifu Packaging Group has a company. The company has passed ISO9001, 14001, 18001 and QS food packaging certification. It is a QS certified laminating factory in Shanghai.
