Wrinkle phenomenon: The main reason is the paper through the heat pressing mechanism, not flat nature of receiving heat and pressure, but have a vertical or diagonal creases, and more in their drag shoot site. Creases ② plastic film: The main reason is the film occurred during transport, the tension will make the film because of improper traction, large or small, leaving the film appear oblique, longitudinal or transverse wrinkles. ③ paper and film together wrinkle: After pressing engagement means of plastic film and paper, in tow tip portion occurs on both sides of the longitudinal or central portion of the outward wrinkles. Film blistering causes and solutions. . Packed packaging must be strong enough, so that it can wrap meals customer without it falling off. Similarly, drinking cups must be able to remain unchanged in the humid environment, it will not let the coffee flow onto the customer's lap. The main factor is the strength of the frozen food under consideration, since frozen food packaging can not freeze / thaw cycles deformation, tearing, distort or absorb too much moisture. On this aspect in terms of practicality, kraft bleached kraft homogeneous than good. Feature refined kraft paper ordinary kraft paper improved products, light color and distinctive appearance clean, smooth and high, good strength, good refined kraft paper printing results. Characteristics and Uses: In kraft paper for the substrate, coated with rubber / hot melt adhesives made of pressure-sensitive adhesive tape. Easy to use, easy to tear off paper bag market with highly adhesive, it is widely used light and heavy packaging sealing, paper processing industry connections use and environmental requirements higher seal packaging. Storage and use of the environment: The product should be packed and stored in a cool, dry environment, avoid sunlight, freezing and high temperatures. Save the environment 20 ℃ ~ 30 ℃, avoid placing excessive heat. Here the focus is whether to punching or cutting, paper bag, generally involves stamping or cutting, triple paper-plastic bags, will be required thickness of release paper, metallized paper-plastic composite bags, because of the low weight at the time of release paper for punching, easy thrust, of course, this is also about the fragility of the end of the paper, fragile paper at the end of a bad time in stamping or cutting paper and products will tear. less than ideal or desired effect. paper bag packaging _ _ Yu Xin Chemical paper-plastic bags provided by Xiong Yu Xin plastic packaging plant. Paper bag packaging _ _ Yu Xin Chemical paper-plastic bags are Xiong Yu Xin plastic packaging plant (www.xinyusl.com) (www.xinyusl.com) this year introduced a new upgrade, the above picture is for reference only, please You call Tel picture on this page or to obtain the latest information, contact: Wang Kai Lai.
