Release time: 2019-12-11 Wuhan direct-sale shrink film label manufacturers offer preferential prices and welcome cooperation. Wuhan Packaging Materials Co., Ltd. welcomes you to visit the factory to watch shrink film labels, ops shrink film The production process of the label presents you with detailed product information and quotations, allowing you to better understand the production process of the product and the price on the market. According to different sealing methods, the packaging effect of different packaging products is also different. There are many types of sealing methods. Next, the heat shrinkable film manufacturer will introduce the sealing method of the heat shrinkable film hot pressing. Let's take a look at the two contact surfaces of the heat shrinkable film to make it in a melted shape, and then increase The pressure makes the contact surface firm and becomes a whole, which can play a series of effects such as beautiful packaging. Good transparency and light transmittance of 80%, can display products, can invisible promotion of products, but also reduce the distribution errors in the logistics link. Moisture-proof, waterproof and dust-proof, it can not only achieve the packaging effect, but also protect the product beautifully. Non-toxic, odorless and pollution-free, it is an environmentally friendly packaging material. The main uses of heat shrinkable film are food packaging fast food, dairy foods, beverages, snacks, beer and various alcohols, agricultural and sideline products, dry food, native products, labels and product sealing; non-food packaging labels and sealing , Fiber and clothing, sporting goods, electrical products, pharmaceuticals, grease, detergent, stationery, toys, office supplies, kitchen utensils, daily necessities, groceries, construction materials and other packaging. The effect of heat sealing temperature on the heat sealing strength of shrink film heat The sealing temperature directly affects the heat sealing strength of the heat shrinkable film. During the packaging or bag making process, if the heat sealing temperature is set incorrectly or adjusted incorrectly, the following two situations will occur. When the heat sealing temperature is too high, it exceeds the heat When the heat shrink temperature of the surface layer material of the shrink film, it will cause the film body to shrink and deform, resulting in adhesion between the shrink film and the heat sealing knife, and the heat sealing edge material is melted and extruded, causing undercutting. When the heat sealing temperature is too low , There will be poor heat sealing. Shrink packaging has good shock resistance, impact resistance, and good protection; temperature is a factor that affects the sealing effect. If the temperature is too high, it will easily cause deformation of the contact surface and affect the appearance. Too low will easily cause problems such as lax sealing. The heat shrinkable film manufacturer tells everyone that resistance heating and pulse heating are two commonly used methods for heat compression, as well as ultrasonic heating, high-frequency current and other methods. Beautiful appearance, can make the film close to the product, so shrink packaging is a kind of skin packaging; it can pack various shapes of goods, and it can shrink packaging of various shapes of goods in the same shrink bag, which is convenient to carry; on One: Brief introduction of PVC heat shrinkable film
