How to seal the heat shrinkable film
heat shrinkable film, which will shrink in case of heat and tightly wrap on the product
PE heat shrinkable film is widely used in the whole package of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact and tear resistance, is not easy to damage, is not afraid of moisture, and has large shrinkage rate.
PVC heat shrinkable film has high transparency, good gloss, high shrinkage rate, and will become brittle after heat shrinkage, POF heat shrinkable film has the characteristics of high surface gloss, good toughness, high tear strength, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film
comparison of physical properties of POF with PE and PVC shrink films:
the proportion of cost POF is 0.92, the thinnest thickness is 0.012mm, and the actual unit cost is low; The specific gravity of PE is 0.92, the thinnest thickness is more than 0.03, and the actual unit cost is higher. The specific gravity of PVC is 1.4, the thinnest thickness is 0.02mm, and the actual unit cost is higher
POF is thin and tough, with uniform thickness, good moisture resistance and soft texture High tensile strength, high tear strength and adjustable shrinkage. Due to the existence of LLDPE, it has better kneading resistance, thick and tough PE, uniform thickness, good moisture resistance and soft texture
the tear strength is lower than POF, but much higher than PVC, and the adjustability of shrinkage is poor. The kneading resistance is not as good as POF. PVC is thick and brittle, uneven thickness, poor moisture resistance, hard and brittle texture, low strength, low shrinkage and poor kneading resistance

wrap the articles with heat shrinkable film first, and then blow the hot air with an electric hair dryer. It’s good to see that they shrink to the shape you want. Don’t just concentrate and disperse
heat shrinkable film, which will shrink in case of heat, so it is tightly wrapped on the product
the correct way to use the heat shrinkable film is to wrap the object with the heat shrinkable film first, and then blow the hot air with the electric hair dryer. It’s good to watch it shrink to the way you want. Don’t just concentrate and disperse it, otherwise it’s easy to burn and rot, and finally seal the mouth.
see what kind of shrink film you make & nbsp; If it is PE polyethylene shrinkable film, it is not a hair dryer. Professional gas shrinkable gun is required. If there is a shrinkable furnace, there should also be a shrinkable furnace specially used for PE to realize
how to seal the heat shrinkable film? How do you say to seal it? It’s simple! Use this heat shrinker! Make the size of the film, cover the film, throw it into the machine, and heat shrink and seal it after a while! Very simple! There is also a simpler one. The machine is not required.
