The problems that should be paid attention to in paper plastic packaging
When packaging a single instrument, the paper and plastic packaging materials with appropriate size should be selected; the sharp tools should be wrapped with small pieces of yarn and then put into the paper and plastic packaging to prevent the packaging bag from being punctured in the process of storage and transportation. When packaging the equipment, the remaining space at one end of the seal is slightly larger, and the distance between the article and the sealing place is 3-5 cm, which is convenient for preventing the paper plastic packaging material from wrinkling during sealing. Keep the plastic on the side if possible.
The sealing machine with the temperature of 150-180 ℃ is selected. The temperature is adjusted at 180 ℃ and the width of plastic sealing strip is 2 cm. The double-layer sealing is adopted for the packaging film to ensure the sealing tightness and tension resistance.
When taking and placing, hold the paper layer by hand. Do not squeeze the paper layer when checking the package. If there is resistance or damage, do not put the package upside down or drag it by hand to prevent one side of the paper from being torn. The inspection method of paper plastic packaging materials is used. After sterilization, pay attention to color change and bag sealing, and pay attention to moisture-proof and sharp instrument puncture. Pay attention to check whether there is any damage when using. If it is damaged, it is forbidden to use it
Expand knowledge: BOPP film is the most commonly used printing substrate, its mechanical strength, air tightness, moisture resistance, cold resistance and other good, and this kind of packaging film transparency is excellent, but poor heat sealing, tear resistance. Its luster is better than that of ink. The key point of its production process is a typical plastic gravure printing - inner printing process. It is printed with polyamide or chlorinated polypropylene ink, with proper tension and printing pressure, and drying temperature controlled below 80 ℃, the color is bright, bright and beautiful after printing. In order to prevent ink from contaminating food, it is often compounded with PE film, so that the ink is sandwiched between the two films. www.dgbpk.com/
