Mesh Bag Morphological Control
- Oct 17, 2017 -

In order to improve the gloss of mesh bag, it must be improved to improve the brightness, but also to eliminate light modification. In addition to the selection of raw materials, we also need to add brightening method, blending method, Shape control brightening method, forming equipment finish control, Mesh Bag two times processing brightening method and surface coating method, especially the use of additives.

1, bag weaving method is divided into two categories: flat-woven mesh bag and warp-knitted mesh bag.

2, flat woven mesh density is different according to the latitude and longitude,Mesh Bag divided into large mesh bag, mesh bag, mesh bag three kinds.

3, warp-knitted mesh bag according to the density of different, divided into large mesh bag and small mesh bag two kinds.

4, bag manufacturers in the appearance of product quality also has strict requirements:

5, Color: The same batch of mesh bag products should not be significantly different.

6, stain: Not allowed to have obvious pollution.

7, Bag Edge: Not allowed to have obvious irregular convex.

Plastic Mesh bag Cost is low, and in many applications embody good attributes. Plastic mesh bag odorless, tasteless, non-toxic flammable white powder, is usually inert, even if the erosion of oxidation is still inert. Mesh Bag Its resistance to chemical reagents increases with the increase of crystallinity. Because of the problem of plastic bag material, he can be applied to various packaging environments without affecting our use.

and waste plastic mesh bags can be recycled, which can greatly save our production costs, Mesh Bag but we have to check the quality of the problem and the presence of toxins before purchase.

PP Plastic mesh bag is a kind of semi crystalline material. It is harder than PE and has a higher melting point. Because the PP temperature is more brittle than 0C, many commercial pp material is a clamp copolymer with no regular copolymer or higher ethylene content of 1~4% ethylene. Copolymer-type PP material has a lower thermal distortion temperature (100C), low transparency, low gloss, low rigidity, but has a stronger impact strength. Mesh Bag The strength of PP increases with the increase of ethylene content. PP's dimension card softening temperature is 150C. Because of the high crystallinity, the surface stiffness and scratch resistance of this material are very good. PP materials have excellent resistance to hygroscopicity, acid and alkali corrosion resistance, solubility. However, Mesh Bag it has no resistance to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents and so on.
