Description of EVA Film

 

EVA film is based on EVA resin which basis to ethylene and vinyl acetate copolymer resin, by adding a variety of modified additives, through melt extrusion made of the rmosetting hot melt film. Not be sticky in normal temperature, easy to operation. Produced by thermal lamination with the bonding enhanced crosslinking chemical reactions, making silicon wafers, glass, TPT multilayer material consisting of one firm bond as the product of solar panels, in actual outdoor applications up to 25 years life. A large number of applications at home and abroad well-proven solar panels, EVA film is the optimum cost performance, it is difficult to alternative packaging materials for solar cells.

Q:What is the density of the common PE films?
Its density is about 0.92g/cm3. Low density polyethylene film transparency and good sealing performance, waterproof, moisture-proof; low tensile strength, tensile elongation, easy wrinkled, thin film below 0.03mm, tension control should be small, and all the tension to a constant, especially easy to deform when heated, causing difficulties in color. Therefore, when drying, the film surface temperature should not be too high (within 550C). According to the film forming process, can be divided into blown film, cast film (IPE) (CPE), several low foaming film etc.. IPE thin film tensile strength and opening than CPE film, with positive printing, can be used for food bags, clothing bags; CPE thin film thickness uniformity, surface gloss, transparency and thermal sealing is better than PE, but positive and negative printing, but the production cost is higher. CPE film is mainly used as the inner layer of composite bags and cosmetics, pickles and pastry packaging; low foaming film decorative, thick texture, not easily tensile deformation, using positive printing, as New Year paintings trademarks and hand bag etc..
Q:Is it good to use paper bags or plastic film bags?
With asbestos mesh (general dish pack more use of this media) direct contact with the disk, the relative effect is better
Q:What kind of plastic film is a little sticky and can be affixed to the label perfectly? What is it like a sticker?
I'm afraid you don't have that. The mucosa is not expensive. When you run out of it, throw it away and change it again.
Q:Genuine Clinie mask packaging has no plastic film
If that is the box, is not only a plastic, paper shell. If it's one of those dozens of pieces sold in one bag, then it's a plastic bag. I just went to Korea on New Year's day. I remember it very well.
Q:A concrete cover film, under what circumstances to cover, what does not cover
The hydration heat of the cement requires only twenty percent of the actual water, and the rest will evaporateAll water evaporates to form a contraction
Q:Is there any toxicity in the production process of plastic blown film machine?
Plastic film blowing machine in the production process is not toxic, film blowing machine production simply by changing the plastic particle morphology, no chemical reaction, if in the production are how toxic these bags have so much for food packaging!
Q:Does the plastic film on the bank card fall off and affect the use?
Whether the bank card can be used depends on the specific circumstances:1, if only the bank card surface plastic film fell, bank cards can be used.2, as long as the bank card black magnetic stripe is not worn or damaged, you can use it normally.3, the easiest way is to check the balance on the bank self-service machines. Bank cards are normal if you can check them.
Q:Can electrostatic generator adsorb plastic film?
The output of the electrostatic generator in the electrostatic discharge generator is positive and negative, and some positive and negative can be converted. Their voltage is bipolar, high-precision, and the output is continuously adjustable. The utility model is suitable for more application fields and the requirements of the new standards in the future, so the electrostatic discharge generator can be used for the electrostatic discharge test of most electrical and electronic equipment.
Q:What's the thickness of plastic film 5C?
Is a light texture, transparency, non-toxic, tasteless new plastic packaging materials, products can be wet, buffer, insulation and so on.
Q:How many days can the concrete be taken away from the concrete?
Cover water conservation according to the outside temperature in general should be concrete after pouring 3 material 12h with straw, Luxi, sacks, sawdust, wet soil and wet sand of the concrete cover, and regular watering to keep moist. Concrete watering maintenance date, Portland cement, ordinary cement and slag cement mixing concrete may not be less than 7 days and nights. Mixing with retarding admixture or concrete with impermeability shall not be less than 14 days and nights; when using bauxite cement, not less than 3 days and nights. The number of daily watering can keep concrete with sufficient moist condition is appropriate, when the air temperature is above 15 DEG C, in the concrete pouring after 3 days in the daytime, at least every 3 hours a night should also be watering, watering two times, after the maintenance, at least 3 times every day watering (of course, when the temperature of the drying can increase the number of water right). For the larger area (or volume) of concrete, should adopt the "water conservation" for reservoir engineering in the demolition of the internal model, concrete reaches certain strength water conservation; to the underground structure or foundation, can be renewed by brushing the surface of asphalt emulsion or soil backfill instead of water conservation.
PROTECT, is the professional manufacture Enterprise with the largest investment scope, the most comprehensive product Specifications, strong production capacity and the highest sales volume, mainly produce special materials PVB and EVA film for bullet-proof glass, windscreen of the automotive, architectural safety glass as well as solar cell panel.
