How to choose qualified corrugated plastic sheets?

(1) The sheet is made of non-toxic and tasteless PP polypropylene, which has no harm to the environment and the products used.

(2) The material of the correx sheet is very light and handy, which is convenient for customers to transport and move.

(3) It is very durable, it has the characteristics of impact resistance and abrasion resistance, but it can be used repeatedly for 5 years or more.

(4) It has anti-corrosion, moisture-proof and mildew-proof functions, and can be used repeatedly and recycled.

(5) The pp corrugated sheet also has the characteristics of bending resistance, aging resistance, stretchability and compression, so it has a wide range of applications.

(6) It can be customized into various colors, shapes and sizes.

(7) It can be antistatic, flame retardant and UV resistant by adding auxiliary materials.

2. Secondly, we must understand the applications of correx sheets

(1) Express delivery industry: In order to save paper resources and protect the environment, more and more logistics companies choose express boxes made of the boards, thereby reducing packaging costs.

(2) Fruit and vegetable industry: Vegetable and fruit boxes made of pp hollow boards have a good preservation effect on the products.

(3) Advertising industry: The corrugated pp sheet has a smooth surface, rich colors and flexible cutting, which is especially popular in the advertising industry.

(4) Hardware industry: It can be designed as a box with dividers, which is very suitable for storing hardware products of different sizes.

(5) Electronics industry: Corrugated plastic sheets with antistatic particles can increase the pass rate of electronic products, so corrugated plastic products can be seen everywhere in the electronics industry.

(6) Decoration: The correx sheet can be used as a protective board for the ground and wall to prevent the ground or wall from being soiled or damaged.

(7) Pharmaceutical industry: The hygienic requirements of the sheet fully comply with the standards of the pharmaceutical industry.

(8) Pet industry: It can be made into a pet house, which is very breathable and refreshing.

(9) Agricultural protection: PP hollow sheets can be used as greenhouse roofs and sapling protection panels, with powerful functions and many benefits.

(10) Catering industry: It can be used as canned or glass bottled food layer pads, effectively avoiding collision and friction between products.

3. Finally, we need to understand the reference index of the pp corrugated sheet:

(1) The thickness and weight standard of the sheet:

• 2 mm-gram weight range 300g-600g gram weight tolerance + – 15 (mostly used for floor protection, sapling protection, separators)
• 3 mm-gram weight range 450g-1000g gram weight tolerance + -20 (used for advertising boards, packaging, layer pads)
• 4 mm-gram weight range 650g-1200g gram weight tolerance + -20 (used for advertising boards, packaging, layer pads)
• 5 mm-gram weight range 850g-1500g weight tolerance + -25 (used for boxes, advertising boards)
• 6 mm-gram weight range 1200g-1800g gram weight tolerance+ -30
• 8 mm-gram weight range 1800g-2000g weight tolerance + -50
• 6-10 mm correx sheet is used in construction

(2) The grade of the fireproof correx sheet

• V0 flame-retardant corrugated plastic sheet is also the highest-level flame-retardant correx sheet. The flame is extinguished within 30 seconds, and there can be no hollow plate burning material falling.
• V1 flame-retardant pp hollow sheet, the flame is extinguished within 60 seconds, and there can be no burning material falling from the correx sheet.
• V2 flame-retardant correx sheet, the flame goes out within 60 seconds. There can be correx sheet burning material falling.

(3) The surface resistance of the anti-static coroplast sheet is 10^6-10^9 Ω

(4) The surface resistance of the conductive coroplast board is 10^3-10^6 Ω

4. Our pp hollow sheets of different specifications have corresponding certificates. While understanding these parameters, we also need the manufacturers to provide corresponding certificates.
