Melt production involves the mixing of additives such as color masterbatches, resin blending, and repulverization. The finished melt must be uniform in concentration and temperature. The pressure must be large enough to squeeze out the viscous polymer.
The rubber extruder performs all the above processes through a barrel with a screw and a spiral. The plastic pellets enter the barrel through a real hopper of the barrel, and then are transferred to the other end of the barrel through the screw. In order to have sufficient pressure, the depth of the thread on the screw decreases as the interval to the hopper increases. External heating and internal heat generated by friction between the plastic and the screw soften and melt the plastic. Different polymers and different applications often have different requirements for the design of the... less
Label updates:
Sooner or later, the BOPP labels of brand-name products will become obsolete, so it needs to be revised after a period of time. For example, the label of ivory soap has changed the font size and shape 18 times since the 1890s. OrangeCrush... moreLabel updates:
Sooner or later, the BOPP labels of brand-name products will become obsolete, so it needs to be revised after a period of time. For example, the label of ivory soap has changed the font size and shape 18 times since the 1890s. OrangeCrush beverages have significantly revised their labels due to the use of fresh fruit labels by competing brands. The new design symbolizes freshness and has stronger and deeper colors.
Legal restrictions on product labels:
For a long time, the law has restricted labels. Poor labels can cause misunderstanding to customers, or fail to describe important components of products, or provide adequate safety warnings. The US federal and state governments have targeted labeling legislation, the most important of which is the Fair Packaging and Labeling Act of 1966. In recent years, the label decision has been affected by unit price (indicating the price of each standard unit), unsealing period (indicating the shelf life of the product), and nutrition labeling... less

Speaking of rubber extruders, I believe everyone is not unfamiliar. To be honest, rubber extruders are a basic equipment of the rubber industry and one of the key equipments that affect product quality. Important role.
The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages. The rubber extruder is a rubber machine used to extrude treads, inner tubes, hoses and various rubber profiles. It is also used to cover cable and wire products. Common is the screw extruder. When it is working, the rubber compound is stirred, mixed, plasticized and compacted in the barrel by the rotation of the extrusion screw, then moved toward the head, and finally extruded from the mouth. Shaped products. For mechanical products, we have to use them in accordance... less

Ordinary film labels are generally PE, BOPP film stickers (with glue on the back), which can be flexo, embossed, screen printed, offset printed. The surface is protected by waterproof varnish; it can be pasted with a labeling machine,in mould labels: The material and printing are the same as above, but there is no glue. It is placed on the mold wall when the bottle is blown. After the bottle is blown, the label is directly embedded into the surface of the bottle and integrated. At present, the special technology and processing of such labels include foaming inks, which can touch the three-dimensional effect of the text, cold or hot stamping, and the hot stamping part has a metallic texture. That's it. less
