Basic overview and characteristics of coaming box
The cover hollow board hoarding box is made of polypropylene material blended with polyethylene material and extruded through the plastic hoarding box production line. , The thickness is also adjustable, and the thickness of the plate in some foreign factories can reach 12mm.
The cover hollow board coaming box is generally made of environmentally friendly and pollution-free recyclable thermoplastic polypropylene (PP), polyethylene (HDPE) resin and various accessories, with high transparency, light weight, impact resistance, sound insulation, heat insulation, difficult It is a kind of high-tech, excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet with characteristics such as combustion and anti-aging. It is a plastic building material widely used in the world.
Hoarding box is a new type of environmentally friendly packaging material, which will not generate dust during use, and has a long service life, which is more than 4-10 times that of corrugated cardboard. It can be recycled and gradually replace paper-made corrugated board The trend is mainly reflected in the product packaging. The plastic hoarding box is light in weight, good in durability, flexible in size and relatively low in cost. The PP plastic hoarding box turnover box formed with various accessories has the momentum to replace the injection molding turnover box.
The material of the coaming box plate determines that it has the functions of non-toxic, non-polluting, corrosion-resistant, waterproof and shock-proof. Therefore, hollow board hoarding boxes are used in areas with high fire protection requirements, such as Christmas supplies, outdoor billboards in monotonous air; blending with anti-UV masterbatch becomes anti-aging and anti-ultraviolet PP plastic hoarding box turnover box, and the application It is used in the construction of greenhouse roofs; it is mainly used in the packaging turnover of factory products in China.
After a series of post-processes, anti-static plastic hoarding box turnover box, anti-static plastic hoarding box knife card, conductive plastic hoarding box turnover box and conductive plastic hoarding box knife card can be formed.
General characteristics and types of coaming boxes
There are basically five types of hoardings for the hoarding box: low-foam sandwich hoarding, double-layer plastic or blow molding hoarding, honeycomb hoarding, X-shaped wave hoarding and traditional plastic hollow board hoarding
The material of the hoarding box is basically PP and HDPE, and the gram weight is 2000-4500g per square meter. In theory, the larger the gram weight, the better the performance.
The characteristics of the low-foam sandwich coaming are: excellent load-bearing performance, good impact resistance, and the length, width and thickness of the coaming can be customized arbitrarily. Suitable for loading bulk particles and liquids. The characteristics of high-priced double-layer blister or blow-molded hoardings are: Blow-molded hoardings are mainly produced by Shoehner. The impact resistance is very superior, and the load-bearing performance is slightly lower.
The disadvantage is that the cost of customization is extremely high, customizing new specifications (no matter whether the length, width and height are different from the standard specifications, it needs to be customized), and the custom hoarding needs to reopen the double-layer blister or blow molding mold. The mold price ranges from 150,000 to 400,000. In addition, due to the molding specifications of the equipment, it is impossible to form super-large coaming boxes.
Honeycomb enclosures should be widely used: excellent load-bearing performance, good welding performance, length, width and height can be customized without mold cost; suitable for bulk particle packaging and liquid packaging; suitable for super-large packaging; high material utilization rate; moderate price. X-type wave hoarding has better load-bearing performance, better impact resistance and moderate price.
