FAQ

Is plastic film the same as glass cloth?

The material is different, not to mention the process

The plastic film on the TV screen doesn't need to be taken

Protective film on the side of the TV should be torn off. The reasons are as follows.1, the protection film affixed to the edge of the TV will lead to poor cooling after the TV is started, thereby affecting the life of the components inside the tv;2, protective foil is also easy to cause the border plastic heating discoloration.

Does the plastic film on the bank card fall off and affect the use?

The damage of the plastic film on the front of the bank card does not affect the use of the card. The key is the magnetic stripe on the back of the bank card. If the magnetic stripe is valid, your bank card can be used normally. It doesn't matter.

Is plastic film made of turning? Is the machine expensive?

New varieties of polyethylene produced in recent years on the international market of low pressure polyethylene (HDPE) and linear low density polyethylene (LLDEP). Because of its excellent impact strength, penetration resistance, resistance to low temperature performance, especially for thin film (1.5 foot thick film strength wire can be arrived at thick wire 3 high-pressure polyethylene film). The use of low cost and therefore large amounts of blown film. However, because of the high melting viscosity and high flow index of LLDPE and HDPE, the ordinary single screw extruder widely used in our country can only produce LDPE film.

What's the performance of PE plastic film?

Heat sealing property. LLDPE film has good heat sealing property. As long as the minimum sealing temperature is reached, it has good heat sealing strength, and has strong sealing and anti pollution ability.

Why should antistatic treatment be applied to plastic film printing? What are the treatment methods?

When printing large width plastic film, large area static electricity is produced due to large contact area. If the machine speed is fast, and the original resin is not doped with antistatic agent, light will affect the quality of the product, deterioration of labor conditions. Heavy fire may cause fire or explosion.

What are the LLDPE plastic films and what are the main uses?

The properties of the resin are generally reflected in the melt index and density. The melt index reflects the average molecular weight of the resin and is mainly controlled by the reaction temperature. The average molecular weight has nothing to do with the molecular weight distribution (MWD). The influence of catalyst selection on MWD.The density is determined by the concentration of the comonomer in the polyethylene chain. The monomer density is used to control the number of short branches (whose length depends on the type of comonomer used) to control the resin density. The higher the concentration of comonomer, the lower the resin density.Structurally, LLDPE differs from LDPE in the number and type of branched chains, while high pressure LDPE has long branched chains, while linear LDPE has only short branched chains.Structurally, LLDPE differs only from HDPE in the number of short branches. HDPE has fewer short branched chains and therefore is of higher density.The physical properties of LLDPE are controlled by its molecular weight, MWD, and density.

How to deal with plastic film greenhouse joints?

Sticking method. Is mainly used for vinyl chloride resin adhesive bonding repair plastic PVC film, polyethylene film of polyurethane adhesive available repair, sometimes small hot hot rolling steel blade available.
