What is the general heat sealing temperature of PET PE composite film?

How thick is the PE film? As far as I understand, it's generally around 160 degrees. You can go to the PP forum, there are many friends who do PE film and PE particles, and there are also those who are engaged in composite film.

PE and PET are two separate materials, which are polyethylene and polyester plastic cooktops, respectively. The composite material formed after composite treatment has the advantages and characteristics of two materials, and is often used to make packaging bags, plastic wrap and other products. However, the sealing temperature of composites can vary depending on the composition and proportions.

The "9-filament PE and PET synthetic material composite film" mentioned here needs to understand the specific structure and composition ratio of this composite material before determining its appropriate heat sealing temperature gauge bridge. In general, the packaging of composite materials needs to be selected according to the heat sealing temperature of different chemical compositions. Some common temperature data are as follows:

PE and PE compounding, the heat sealing temperature is usually controlled between 120-140 degrees - PE and PET compounding, according to the combination ratio of the heat sealing temperature is about 130 160 - PET and PET compounding, the heat sealing temperature is generally between 200-230 degrees, but the specific high difficulty heat sealing temperature needs to be determined according to the thickness of the composite film, composite components, atmosphere and other factors, it is recommended that you follow the recommendations of the manufacturer or raw material manufacturer. When operating, please strictly abide by the operation specifications and safety tips of the manufacturer or sealing machine manufacturer to ensure that the operation process is safe and reliable.

Summary. Pro-kiss, PE film can improve the heat sealing temperature range by treating it with the following methods:1

Modified PE films with a wider range of heat sealing temperatures, such as metb, VLDPE, etc., can increase the heat sealing temperature. 2.Adding an appropriate amount of plasticizers, such as starch, glycerin, etc., to the PE film can soften and plasticize the PE film to a certain extent and expand its heat sealing temperature range.

3.A heat-sealing layer is applied to the surface of the PE film, and this coating is specially designed for heat sealing to expand the heat sealing temperature range. 4.

The PE film is cross-linked using an electron beam or UV treatment to increase its heat sealing temperature range. 5.Instead of the heat sealing process, a two-component solvent-based heat sealant is used to achieve bonding by solvent softening and dissolving the film layer.

6.Non-contact heat sealing technologies such as RF radio frequency, ultrasonic, and laser are used to improve the accuracy of heat sealing. 7.

Optimize the parameter settings of the heat sealing equipment, such as temperature, pressure, time, etc., to obtain a wider heat sealing window. 8.The film material is pretreated at the heat sealing site, and the crystallinity is enhanced by means of flame and plasma.

Choosing the appropriate treatment according to the specific use of the PE film can achieve the best heat sealing effect that does not overwhelm the pants and does not overwhelm the fragility of the pants and does not cover the skin too soft. Hopefully, the above information will provide a reference for kissing. If you still have any questions, please feel free to communicate with me <>

Summary. To improve the heat sealing temperature range of PE film, the following methods can be used:1

Choose PE materials with high melting points: Choose PE materials with higher melting points, such as high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMWPE). These materials have a high melting point and thermal stability and can withstand higher sealing temperatures.

2.Add heat stabilizer: Adding heat stabilizer to PE film can improve its high temperature resistance.

Heat stabilizers resist thermal degradation and delay the aging process of the membrane material, thereby increasing the temperature range of heat sealing. 3.Adjust the thickness of the film:

Increasing the thickness of the PE film can improve its high temperature resistance. Thicker film materials are better able to withstand the heat sealing process at high temperatures, thus increasing the heat sealing temperature range.

Thicker film materials are better able to withstand the heat sealing process at high temperatures, thus increasing the heat sealing temperature range.

Use of copolymers: Copolymers are polymers that are impertured by the polymerization of two or more different monomers. The addition of copolymers to PE films can improve their heat sealing properties and increase the heat sealing temperature range.

Change the parameters of the heat sealer: adjust the parameters such as temperature, pressure and sealing time of the heat sealer, which can adapt to different PE film materials and heat sealing temperature requirements. Use of coating technology:

Coating a layer of high-temperature and durable coating on the surface of the PE film can enhance its high-temperature resistance.

The heat sealing of PE will generally be larger, which will be greater than its own tensile force, and it also depends on the thickness and use of PE film.

Generally speaking, the heat sealing strength of ordinary PE film will be greater than 6N, and the cooking grade will be greater than 30N
