The transverse shrinkage rate is 48% to 53%, and the longitudinal shrinkage is about 1% to 3%. The shrinkage temperature is 90 to 120 degrees Celsius. Currently on the market, there are labels for various types of beverage bottles such as green tea and nutrition fast. Used in all kinds of printing, digital fast printing, business card design, self-adhesive printing, self-adhesive color printing, photo / inkjet / decoration, engineering drawing processing, engineering drawing printing, engineering drawing, KT board design, outdoor advertising, recipes , menu design, menu glue, high-end recipe binding, all kinds of book binding, all kinds of binding methods, color page design, leaflet design printing, mass copying, receipt printing, etc., pvc is generally divided into hard and soft two The plasticizer content of less than 20% is hard and your toughness can be increased by adding more plasticizers and pit impact mbs.
The main body is polyvinyl chloride resin, and some other additives that must be added to PVC, such as stabilizers, lubricants, impact modifiers and plasticizers.
PVC heat shrinkable film is widely used in our lives. PVC heat shrinkable film is made by mixing ethylene resin with more than ten kinds of auxiliary materials and then inflating it twice. The method of using it is to calculate the circumference according to the size of the package, and convert the diameter of the package (folding diameter = 1/2). Perimeter), then enlarge the folding diameter appropriately. PVC heat shrinkable film is selected according to the product specifications of the factory, and the suitable and PVC heat shrinkable sleeve film is selected. The sleeve film is placed on the packaged object, and the temperature is between 100 ° C and 160 ° C for 6-10 seconds (the sleeve film is actually heated to a temperature of 86 ° C and the left glaze winter package is heated to less than 10 ° C). .
