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:Can the plastic film on the lens of the swimming mirror be removed?
This film can be removed and should be removed because it is used to protect the lens and should be removed before the consumer officially uses the swimming mirror, otherwise it will affect the transmittance of the swimming mirror.
Q:How often will the plastic film in the greenhouse be replaced?
In actual production, once a year. Although now the film is very durable, but light, fog, dripping the new film or better.
Q:Can I use plastic film to make roofing waterproof?
No, roof waterproof is a crucial step.
Q:How are membranes classified?
Linear low density polyethylene film. LLDPE film is a new variety of polyethylene film developed recently, compared with the LDPE film, LLDPE film has higher tensile strength, impact strength, tear strength and puncture resistance is. With the same strength and service performance as LDPE films, the thickness of LLDPE films can be reduced to 20 to 25% of LDPE films, thus greatly reducing the cost. That is, the use of heavy packaging bags, the thickness is only 0.1, L can meet the requirements, can replace the more expensive polymer high density polyethylene. Therefore, LLDPE is suitable for daily necessities, frozen food packaging, but also a large number used as heavy packaging bags and garbage bags.
Q:Several forming methods of plastic film and their advantages and disadvantages are summarized
Tape casting, blown film and calendering, the physical properties of cast films are better than blown films.
Q:Why should plastic film be compounded? What are the composite soft packing substrates?
In the actual use of plastic flexible packaging, due to the different shape and physical properties of the package, the protection performance requirements are also different.
Q:Why use plastic film wrapped legs running, weight loss good?
Plastic film weight loss is unscientific, and can not fundamentally reduce weight. Because of the use of plastic wrap body, affect the surface heat, causing the local temperature increase, increased perspiration, causing local fat cells and other tissue cells of the water temporarily outward penetration, but it does not increase the consumption of fat.
Q:Should the film on both sides and back of SIEMENS refrigerator be torn off?
The SIEMENS refrigerator on both sides and the back of the film should be torn off.
Q:What's the plastic film on the disposable paper cup?
The wax coated cup is coated with a layer of wax used to separate the water.The polyethylene film cup is the film covered with polyethylene in the cup wall.The wall of the double wall cup has two layers of paper. There is air between the paper and the paper, and the insulation is very good.
Q:How to choose PE plastic packing film
Welding strength is also a necessary condition for plastic film bags to protect goods reliably. If the weld strength is not enough, the weld will become the fatal weakness of the plastic film bag, and the plastic bag will lose the protection to the goods because of the rupture of the weld seam.
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.
