Beijing heat shrinkable film label manufacturer low price direct sales are sought after by customers Release time: 2020-01-15 Beijing heat shrinkable film label manufacturer low price direct sales are sought after by customers, Wuhan Packaging Materials Co., Ltd. has sold heat shrinkable film since its establishment Labels, ops heat-shrinkable film labels and the praise received are our driving force, we are your wise choice. Chemical performance resistance to atmospheric chemical trial production and biological trial production, insulation properties, resistance to electricity, heat insulation, noise reduction; other physical properties Waterproof, greaseproof and airtight' can be collapsed into hard or soft transparent or opaque products according to requirements; can be welded or heat sealed by high frequency; easy to color and print. The processing performance is easy to adopt all the processing technologies in the current plastic processing. Such as injection molding, extrusion, Huan plastic, rolling, coating, etc. The heat shrink packaging machine can be processed and cut arbitrarily, and is commonly used in molds, hydraulic presses, and other parts that need heat insulation, and can also be used for self-made roofs and other parts that need heat preservation. Save energy, reduce heating time, reduce heat conduction to equipment, and have a good insulation effect. Some small material manufacturers did not grasp the uniformity of the coating when coating the adhesive, resulting in uneven thickness of the adhesive layer. The self-adhesive labels produced with this material are prone to cut through the backing paper during the die-cutting process. Die-cutting failures caused by this reason are usually irregular, that is, when the die-cutting pressure does not change, the phenomenon of cutting through the bottom paper and not cutting through the bottom paper will appear disorderly. It is recommended to replace the self-adhesive material when encountering this problem. Die-cutting bottom plate material problem When most flat-bed die-cutting equipment is working, it is necessary to pad the die-cutting bottom plate under the die-cut material to avoid direct contact between the knife plate and the steel plate below, thereby extending the service life of the knife plate. Generally speaking, the die-cutting bottom plate needs to choose materials with moderate hardness, certain flexibility, and smooth surface. If the surface strength of the die-cutting bottom plate is not enough, it will be easily deformed after being impacted by the knife plate during the die-cutting process, which will cause the local pressure of the die-cutting to change and cause the bottom paper to be cut or even cut through. The main properties of the heat shrinkable film are mechanical properties, strong, light weight, durable and scratch resistant; the four products are not brand new materials, produced with recycled materials, or added recycled materials, resulting in reduced tensile force and easy to break. The self-adhesive label is mainly composed of a three-layer structure. The surface material is coated with a silicone oil layer on the adhesive bottom paper. The ideal situation of die cutting is that the die cutter cuts through the adhesive layer, but does not damage the silicone oil layer, which is called'precision die cutting'. However, in the actual production process, it is impossible to achieve this ideal situation due to the influence of the self-adhesive material, cutting tool, machine and operator factors, and often the bottom paper is cut through and the die-cutting distance is unstable. And other phenomena. Self-adhesive material problems Self-adhesive materials have very high requirements for flatness. With the rapid development of food, cosmetics, medicine and other industries, the demand for plastic composite packaging products is increasing.
