Jilin heat shrinkable film label manufacturer sells rich specifications and good quality directly. Release time: 2020-01-08 Jilin heat shrinkable film label manufacturer sells rich specifications and good quality directly. Wuhan Packaging Materials Co., Ltd. is a heat shrinkable film widely recognized by users Labels, ops heat shrinkable film label manufacturer, supply a wide range of products, reliable performance, high quality, welcome to buy! Thereby affecting its overall aesthetics. Pressure control is necessary for its good strength. Reasonable pressure is also very necessary. Generally speaking, a reasonable and uniform pressure helps to reduce the rate of bubble generation, thereby increasing the overall yield rate and reducing unnecessary losses for the enterprise; so Reasonable pressure is also an important factor affecting the strength of heat shrinkable film. Nowadays, heat shrinkable film covers the packaging field of electronic products, medical products and other industries, and it can be said that it has been widely used. However, in production and use, some problems will inevitably affect the use effect. Then, what are the common problems and solutions for the use of heat shrinkable film. Below, our staff will answer for you to answer the flatulence hot air retained in the shrink film. The solution increases the number of vent holes to speed up the air leakage from the shrink film. Slow down the conveyor belt speed of the packaging machine, so that hot air has a longer time to leak from the shrink film. Increasing the temperature of the packaging machine helps air leak from the heat shrinkable film. The surface of the atomized shrink film becomes blurred, like a mist. Solution Lower the temperature of the packaging machine. Excessive temperature is the cause of the shrink film atomization. Increase the conveyor speed of the packaging machine to reduce the time that the shrink film is exposed to heat. Fish-eye-like wrinkles appear on the surface of the fish-eye heat shrinkable film. Solution The temperature of the shrink packaging machine is too low, and the temperature of the packaging machine can be increased. The speed of the conveyor belt of the shrink packaging machine is too fast, and the speed of the conveyor belt can be reduced. The circulating wind force of the shrink packaging machine is too low, so the circulating wind force can be lowered. Shrink film is very common in the current packaging market, such as the outer packaging of cosmetics and stationery, the outer packaging of doors and windows, the outer packaging of aluminum, and the outer packaging of various stainless steel tubes. Because the shrink film has good shrinkage, strong tensile force, and simple and easy to operate packaging, it only needs to be heated with a high-power hair dryer or a semi-automatic heat shrinking machine, and it can be tightly fixed on the surface of the product. However, some shrink film packaging products are easy to break after a slight touch. What is the reason? I think there are four main reasons for the quality of the shrink film itself. If the temperature is not adjusted properly during production, the quality of the product is unstable, poor durability, and easy to break; the shrink film is made too thin. In order to save packaging costs, some businesses will require manufacturers to make the shrink film thinner, but the shrinking force of the thin shrink film is too large after shrinking, and it will be easy to break; the temperature and time during heating are not well controlled, resulting in unqualified products.
