The lighting paper tray is a new type of paper-plastic paper tray packaging products. When we buy lighting, the inner lining of the cushion packaging is generally made of foam. Although the entry of plastic products into the field of daily life has brought people a lot of convenience, the white pollution caused by some plastic products is also shocking. After the waste plastic packaging enters the environment, it is difficult to degrade, causing long-term, deep-seated Ecological and environmental problems: First, waste plastic packaging is mixed in the soil, which affects the absorption of nutrients and water by crops, resulting in reduced crop yields; second, waste plastic packaging discarded in land or water is swallowed as food by animals. Cause animal deaths (in zoos, pastoral areas, and the ocean, this kind of situation is not uncommon); third, waste plastic packaging mixed with domestic garbage is difficult to dispose: landfill treatment will occupy land for a long time, and domestic garbage mixed with plastic It is not suitable for composting, and the sorted waste plastics are also difficult to recycle due to the inability to guarantee the quality. There are a wide range of sources of molded pulp paper trays. Commercial pulp, homemade pulp, scrap from paper processing and pulp from recycled waste paper can be used as raw materials according to different product requirements. In particular, the use of waste paper pulp can greatly reduce packaging costs. It has a great environmental protection effect, and because the pulp used as a raw material is light and soft, it also has good protection and cushioning properties.
At present, the gradual maturity of the pulp molding manufacturing process has made paper-plastic paper trays more and more widely used. The development and continuation of paper-plastic paper trays in our country have put forward a good point of view, especially for the scope and application of paper-plastic paper trays. Industry applicability research, expounding detailed and reasonable industrial structure layout, has played a guiding role in the development direction of my country's paper support environmental protection cause.
1. Poultry egg paper tray. Because of its loose material and unique egg-shaped curved surface structure, the pulp molded egg tray has better air permeability, freshness retention, excellent cushioning and positioning, and is especially suitable for eggs, duck eggs, goose eggs and other poultry eggs The packaging of large quantities of transportation. Using paper mold egg trays to package fresh eggs, during long-distance transportation, the damage rate of eggs can be reduced from 8%-10% of traditional packaging to 2%. The retail of eggs in Europe and the United States is counted by each individual. Generally, it is made into a pulp molded box that can hold 6 (half a dozen) eggs. The outer surface of the box can be printed with various signs according to user requirements to improve the display effect of the counter. There are three kinds of fresh egg paper trays, zDTP-30-40, zDTP-30-45, and zDTP-30-50 specified in GB 10443-1989 "Pulp Molded Egg Paper Trays", which are used for 40-70g Fresh egg packaging.
2. Fresh fruit paper tray. Pulp molded paper tray can be molded into a paper tray with a fruit surface structure, which is used for the packaging of peach, pear, citrus, apple, pineapple, tomato and other fruits, especially for export fruits. It can avoid collision and damage between fruits and can also distribute The heat of breathing of the fruit absorbs evaporated water, inhibits the concentration of ethylene, prevents the fruit from decay and deteriorates, and prolongs the shelf life of the fruit, playing a role that other packaging materials cannot play.
3. Electrical liner. my country's electrical products use foamed plastics as linings, but developed regions in Europe have refused to import such packaging materials, forcing my country's lining packaging to embark on the road of "replacing plastics with paper" as soon as possible. The use of paper pulp molding material as a cushion has the advantages of good plasticity and strong cushioning force, which fully meets the inner packaging requirements of electrical products, its production process is simple and does not pollute the environment, and the product is adaptable and widely used.
4. Septa for fragile products. In the past, the septa of fragile products such as glass, ceramics and poultry eggs were often replaced by paper scraps and grass, which were not standardized and unhygienic, and the anti-vibration effect was also difficult to achieve. The pulp molded paper tray septum is easy to make, neat and uniform after molding, easy to pack, and has strong cushioning and shock absorption capabilities. Because such products have low requirements for raw material technology, production costs are easy to control, and they are suitable for large-scale production and applications.
5. Agricultural appliances. Mainly used for nutrient bowls of seedlings or other crops, flower and seedling wings, packaging of grain, vegetables, fresh meat, and silkworm grid clusters, such as paper mold bowls used in landscaping and garden planting, which are very large The advantage is that the seedlings do not need to be transplanted twice. After the seedlings emerge, the seeds can be transplanted together with the seedlings and the pots (the pots can be degraded by themselves), which saves labor and time and has a high survival rate. If you are planting trees in areas with poor natural conditions such as mountain deserts The effect of afforestation will be even better.
6. Food (medicine) packaging. In addition to fast food utensils, many medicines, edible semi-finished products, cooked foods and convenience foods can be packaged in pulp molded paper trays, such as clean vegetable paper trays, instant noodle bowls, containers used in the domestic catering industry, etc., which are not only clean and hygienic, but also easy to use and recyclable. Recycling meets the requirements of environmental protection and human health.
7. Medical appliances. The major problem in the use of traditional medical appliances is that cross-infection is likely to be caused by incomplete disinfection. If you switch to various types of disposable pulp molded paper trays, spittoons, bedpans, body pads, splints, etc., you can not only eliminate the disinfection process, but also It saves labor, and its waste can be incinerated directly without toxic side effects. Moreover, the price of pulp molding equipment is moderate, which is easy for both doctors and patients to accept, which brings a lot of convenience to medical care.
8. Pulp molded paper tray packaging for special industries. Some products are afraid of collision, static electricity, moisture, and corrosion, and extreme caution is required in packaging, storage and transportation. The paper mold material can be made into a neutral substance with good cushioning power, strong plasticity, moisture-proof, rust-proof, and anti-static. After adding special additives, its performance can be expanded, and the safety factor in use is large.
