First, the paper holder usually refers to the paper holder in a broad sense, which is the paper holder of the dry pressing process. The English name of the paper holder: Molded Pulp Packaging, referred to as MPP, scientific name: pulp molding, using pulp as raw material, using stainless steel filter mold under pressure (negative pressure or positive pressure) and other conditions, the pulp is dehydrated and the fibers are formed And the processing method to produce the desired product. Paper tray production mainly includes pulp preparation, forming, hot pressing, moulding and other processes. Die forming has vacuum forming method and extrusion forming method. Since the pulp used in pulp molding mostly uses waste paper as raw material, it complies with the requirements of environmental protection and the development direction of green packaging.
Second, what are the application scopes of paper trays?
Its application fields include electronics, electrical appliances, communication equipment, computer accessories, glass, ceramics, lighting, handicrafts, cosmetics, health products, wine, fruit, eggs, etc.
Third, what are the characteristics of the paper holder?
Compared with foamed plastic (EPS) products, paper trays have the following characteristics:
1. The raw material of the paper tray is waste paper, which is easy to recycle and will not pollute the environment, which will be beneficial to the export of the manufacturer's products; the raw material of EPS is petroleum by-products, which are difficult to degrade, and the recycling price is very low, causing serious damage to the environment. "white pollution".
2. The paper tray has a wide range of applications. With the advancement of paper mold technology, the medium and small industrial products that use foam as the inner lining packaging can basically be replaced by paper trays.
3. Paper trays can be stacked and stored, which reduces the storage space occupied by EPS products by 1/2 to 2/5, which can greatly reduce transportation and storage costs.
4. Anti-static: EPS friction is easy to generate static electricity, while the paper holder is not easy to generate static electricity, which plays a better role in protecting electronic products and home appliances, especially electronic components.
5. Anti-corrosion performance: food (such as fruit, etc.) will release water when stored. When it is packaged with plastic products, its water cannot be volatilized, which is easy to make food moldy and rotten, while paper products have good air permeability, and water can be volatilized. out, so as to achieve the anti-corrosion effect.
6. Shockproof performance: The shockproof and shockproof performance of the paper holder is the same as that of EPS products.
Fourth, what is the thickness and weight of the paper holder
1. The thickness of paper support products is roughly between 0.5mm---5mm, and the thickness of general products is mostly maintained at about 1.0-2.5mm;
2. The maximum static load of paper mold packaging products can reach 1500 kg. The lined packaging is the best choice for products weighing less than 50 kg;
The paper mold material mainly depends on the design of the reinforcing ribs of the product and the buffer cavity formed by the reinforcing ribs. The design of the reinforcing ribs plays a vital role in the elastic deformation of the paper mold packaging products, that is, the buffer capacity, and the basic basis for the design of the reinforcing ribs. It is the shape and shockproof requirements of the product itself.
5. What are the main properties of paper tray packaging products?
1. Cushioning performance 2. Waterproof and moisture-proof performance 3. Anti-static performance 4. Completely degradable, easy to recycle, 100% environmentally friendly 5. Oil-proof.
Sixth, what material is used for the mold making of paper support products? How much does it cost to make?
The main materials of pulp product molds are aluminum alloy materials, copper alloys, steel alloys and resins. The production of paper molding products is completed by two pairs of molds, namely forming molds and hot pressing molds. The manufacturing cost of each mold ranges from 6,000 yuan to 20,000 yuan. not wait.
Seven, the wet-pressed paper holder is relative to the above dry-pressed paper holder. The following are the characteristics:
1. Product appearance: high smoothness, the paper holder is molded by the upper and lower molds, and the inside and outside can be as smooth, not rough, and lint-free;
2. Product accuracy: Due to the particularity of the equipment, the mold is processed by the CNC center, the minimum rounded corner can reach R2, the precision is extremely high, and it can fully fit every angle of the product, like a close-fitting underwear protecting the product;
3. Not easy to deform: Through the mold drying process of the equipment, the produced paper holder only contains 1% water, so it will not be deformed due to moisture weathering when stored in nature;
4. Raw materials: log (paper) pulp, sugarcane pulp, newsprint, black cardboard, etc. are used as raw materials for production. There are pure white, milky white, gray, black and other colors for you to choose from, all of which are environmentally friendly materials;
5. Scope of application: Our paper holder is suitable for some high-end, lightweight, delicate and electronic products that are dedicated to improving the added value of expensive products. The company currently supplies paper trays for mobile phones, MP3, digital cameras, set-top boxes, repeaters and small medical equipment.
