Heat transfer film packaging products in people's lives can be seen everywhere, some raw material belongs to renewable material, some are not renewable material, but no matter which at the time of production for the temperature requirements are very strict. The temperature can be said to determine the quality of these products, the temperature is too high or too low will cause a great impact on it, we are going to introduce you the temperature can determine those factors, I hope to help you.

1 temperature can determine the thickness and length of film products. Because the raw material of this kind of products are polyethylene and polypropylene, it needs to pass through the high temperature before they can be melted, the temperature must be reached so that they melt temperature, not too high or too low, the efficiency is too low then the melting is greatly reduced, too high will cause it to increase the degree of melting and what we need is a gelatinous substance, not like a liquid substance, this time to control the temperature of good.

It is necessary to control the tensile temperature after 2 die temperature control, after the film is after several stretching before slowly thinning, if not stretch it will not thin, while stretching the various stages of the temperature is different, in front of the required temperature is very high, after the required temperature very low. In two it also need to put them into the oven inside the annealing treatment, otherwise it will have problems. In short, it is very important for the production of temperature, we must be able to grasp the flexibility.
