What is the net foam package outside apple?

by admin

is called fruit net cover, which is a kind of foamed polyethylene

it is composed of numerous independent bubbles generated by physical foaming of low-density polyethylene grease. It overcomes the shortcomings of fragile, deformation and poor recovery of ordinary styrofoam. It has many advantages, such as water-proof and moisture-proof, shockproof, sound insulation, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, strong collision resistance and so on. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials

extended data:

daily fruit preservation methods

1. Apple. When selecting apples, select late maturing varieties with high hardness, such as red Fuji, and the apples will remain intact without disease spots. Normal temperature and cold storage

2. Grape. When storing grapes, do not wash them first. Put them in fresh-keeping bags and refrigerate them in the refrigerator. When they are taken out, they taste cool and sweet

3. Citrus. Normal temperature is enough. Be careful not to put it with bananas, which will accelerate aging

4. Lemon. For the cut lemon, slice the remaining lemon into fresh-keeping bags and store it in the refrigerator

5. Banana. Bananas are best kept at 7-23 degrees Celsius, so they can’t be put into the refrigerator for refrigeration, otherwise they are prone to frostbite and dark brown spots. The banana handle can be wrapped with tin foil to reduce the release of ripening gas, or the banana can be hung with a clothes hanger to reduce the pressure area and prolong the storage time& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;

Apple’s netted foam packaging is called fruit net

. Its raw material is EPE. It is a new environment-friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene grease. It overcomes the shortcomings of fragile, deformation and poor recovery of ordinary styrofoam. It has many advantages, such as water-proof and moisture-proof, shockproof, sound insulation, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, strong collision resistance and so on

extended data:

polyethylene is a white waxy translucent material, soft and tough, lighter than water, non-toxic and superior dielectric properties. Easy to burn and continue to burn after leaving the fire. The permeability is low, but the permeability to organic vapor is large

the transparency of polyethylene decreases with the increase of crystallinity. At a certain crystallinity, the transparency increases with the increase of molecular weight. The melting point range of high-density polyethylene is 132-135 ℃, and the melting point of low-density polyethylene is low (112 ℃) and wide

it is insoluble in any known solvent at room temperature, and a small amount can be dissolved in toluene, amyl acetate, trichloroethylene and other solvents above 70 ℃

mesh foam packaging is the fruit packaging net. p>

the commonly used material is foamed polyethylene. Commonly known as pearl cotton, it is a closed cell microporous thermoplastic material. There are two kinds of crosslinking and non crosslinking. It is a new environmental protection packaging material with high cushioning, shock absorption and seismic resistance. It is flexible, light, elastic and has good recovery. It can absorb and disperse external impact force through bending to achieve the effect of cushioning. At the same time, foamed polyethylene has a series of superior application characteristics, such as thermal insulation, moisture-proof, anti friction, corrosion resistance and so on. After adding antistatic agent and flame retardant, it shows its excellent performance
