Paper plastic is actually life everywhere in the packaging liner of various products, is a three-dimensional papermaking technology, it is a certain concentration of waste paper pulp, add an appropriate amount of chemical additives (such as moisture-proof agent, waterproofing agent, mildew agent, etc.), in the mold with a screen through the vacuum or pressurized method to make the fiber uniformly distributed on the surface of the mold, so as to form a formulated shape of the pulp molding, and then through the dehydration, demolding, drying and shaping can be used. After dehydration, demolding, drying and shaping, the pulp is ready for use. So which one is energy-saving, dry pressing or wet pressing? The following Mingfeng packaging editorial to give you an introduction.
Which is energy efficient, dry pressing or wet pressing for paper and plastic:
Dry press method paper tray:
1, environmental protection, raw material waste paper, recyclable, no chemicals, no pollution;
2、Protection, containing fibers to form a good shockproof, three-dimensional strength structure of the product with good protection;
3, Storage, can be stacked storage, reduce 1/2 storage space;
4, cost, unit price is lower than styrofoam; product packaging volume is slightly smaller, container more products to reduce costs;
5. Moisture-proof, can absorb excess water during transportation after packing, and strengthen the moisture-proof effect of the product;
6, image, the use of environmentally friendly packaging, can enhance the company's product image, to avoid obstacles to international trade.
Wet-pressed paper trays:
1, raw materials: the use of raw wood (paper) pulp, sugar cane pulp, newsprint, black cardboard and other raw materials for production, the existing pure white, cream, gray, black and other colors for you to choose from, are environmentally friendly materials, sanitation indicators to reach the food grade, through the U.S. FDA testing;
2、Quality: the surface of the product is bright and exquisite, set off the brand product grade, enhance the added value of the product;
3、Technology:using hot press molding technology, high production efficiency, to ensure timely delivery;
4、Environment: designed according to food-grade standards as a fully enclosed air-conditioned production workshop, clean and tidy;
5, product appearance: high finish, paper tray through the upper and lower mold molding, inside and outside can achieve the same smooth, not rough, not hairy;
6, product precision: due to the special nature of the equipment, the mold by the CNC center processing, rounded corners up to R2, very high precision, can completely match every angle of the product, like a piece of intimate underwear to protect the product;
7, not easy to deform: through the equipment of the mold drying process, the paper tray factory production out of the paper tray contains only 1% of water, so the storage in nature will not be deformed due to water weathering;
8, the scope of application: paper tray is suitable for some high-end, lightweight, delicate type and to force to improve the added value of the product electronic products. There are also cell phones, digital electronic products, set-top boxes, cosmetics, repeaters and small medical equipment and other products paper tray.
The above content is on the paper and plastic dry pressure and wet pressure which energy-saving introduction, for the wet pressure process production process is a large amount of water before the hot press, the hot press to solidify the shape of the pulp fibers easier to flow, the surface of the molded product is more flat and smooth, not hairy, no powder, the back of the mesh screen prints, the quality of the process is significantly better than the dry process, is more suitable for packaging is relatively light, small, cost-effective products, so For some high-end products packaging (such as cell phones, computers and televisions, etc.) mainly use wet pressing process production.
