PP hollow sheet is polypropylene raw materials mixed with polyethylene raw materials through the hollow sheet production line extrusion molding, the cross-section of the sheet for the lattice shape, so also called lattice hollow sheet. In some countries, it is also called Twin Wall Polypropylene Sheet, and there are some familiar names such as: plastic hollow sheet, universal board and some people call it honeycomb board, which are all related to people's habits of use. The thickness of PP hollow sheet usually ranges from (2-8mm), and even the thickness of PP hollow sheet of some factories can reach 12mm.
This passage is going to talk about the followings of PP hollow sheet:
1) Introduction to PP hollow sheet
2) Characteristics or advantages of PP hollow sheet
3) Choose our best PP hollow sheet
PP hollow sheet is a new material with light weight (hollow structure), non-toxic, non-pollution, waterproof, shockproof, anti-aging, corrosion resistance and rich color. Compared with cardboard structure products, hollow board has the advantages of moisture-proof and corrosion resistance.
The material of PP hollow sheet decides it has the performance of non-toxic, non-pollution, corrosion resistance, water-proof and shock-proof. Some factories can mix flame retardant masterbatch to make flame retardant hollow board according to different requirements, and apply it in the field with high fireproof requirements, such as Christmas supplies, outdoor billboards in dry air; mix anti-UV masterbatch to make anti-aging and anti-UV PP hollow sheet, and apply it in the construction of greenhouse roof; in China, it is mainly used in the packaging turnover of factory products, among which there are ordinary PP hollow sheet, anti-static PP hollow sheet (surface impedance range between 9-11 times Ω of 10), anti-static PP hollow sheet (surface impedance range between 6-9 times Ω of 10), conductive hollow board (surface impedance range between 3-5 times Ω of 10), after a series of post-process can be shaped into anti-static hollow board turnover box, anti-static hollow board knife card, conductive hollow board turnover box, conductive hollow board knife card.
PP hollow sheet is a new type of environmentally friendly packaging materials, in the use of the process will not produce dust, and long service life, is 4-10 times more than the life of corrugated cardboard, can be recycled, there is a trend to gradually replace the paper corrugated board, mainly in the product packaging. In addition, because of the light weight of PP hollow sheet, good toughness, flexible size, relatively low cost, equipped with a variety of accessories molding PP hollow sheet crates have replaced the momentum of injection molding crates.
PP hollow sheet is PP sheet made of PP polypropylene raw material, it is a material with many advantages, as follows.
1、Excellent glossiness and transparency, and the specific gravity is the lightest one among general-purpose resins.
2、Good light transmission rate: 60%-92%.
3、Non-toxic, odorless, tasteless, good hygiene.
4、Excellent grease resistance, good chemical resistance.
5、Very high impact strength, 200 times that of ordinary glass, 30 times that of acrylic.
6、Good weather resistance, anti-UV.
7、Temperature resistance, in the temperature range of -40 degrees Celsius -120 degrees Celsius can be used.
8、Good sound insulation effect.
9、Easy to install.
10、Trace resistance. On the surface of the hollow board, it is absolutely not easy to appear the phenomenon of scratch, its scratch resistance is very strong.
11、It has moderate lightness and excellent moisture barrier.
12、Poor cold resistance, good heat resistance.
13、Have good heat sealing property.
The most common application of PP hollow sheet due to its special performance should be that the hollow sheet made of hollow board perimeter drilling heart gradually began to replace the previous ordinary cardboard boxes, to be used as a variety of farming industry goods transportation and packaging. Not only that, PP hollow sheet can also be used as ventilation wall panels for breeding houses, space spacers and Agriculture Box materials, etc.
