Food packaging bags can be easily torn

Believe that a lot of friends all have such experience, a bag of food in front of you, but it is difficult to tear apart. If it is in the home, it will be directly with his teeth bite, but embarrassing things to, incredibly bite does not open, the saliva flow out. Food packing bag is strong in order to protect the food, but for us is going to kill food, but not a good thing. In order to solve this things, food packaging technical staff developed laser marking. So that we can taste food easily, no longer awkward. On the laser marking is a multi-layer composite packaging materials using laser to complete easy to tear, can be done on a thin film layer packet, all without damage to the film. Laser marking technology for food packaging of right and wrong, touch and no wear process, also make sure that the packing of goods not damaged because of the packing process, ensure the stability and reliability of products. While traditional marking way to manufacture line is too shallow, which is difficult to tear apart. Sometimes easy line to draw too deep in the traditional way, the food packaging bags made to damage, leaving a small line, the use of impact is the consumer experience and the quality of the goods. In the food packaging processing carbon dioxide laser is the best choice, depending on its transport and adsorption to achieve precise line depth. More bags of food to choose composite membrane, such as PET/AL/PE, PET/CPP, OPP/AL/PE, etc. , their absorption and emission characteristics of carbon dioxide laser wavelength is different, so one of the film has been opened, and the other layer of thin film was not affected. Aluminum foil layer or the other, on the other hand, plating metal layer on the membrane, other materials has become the way to deter a laser barrier layer, so the performance of these materials can make laser technology in packaging materials on the precise positioning, crossed. Food packaging use laser marking advantage: 1, only the selected layer of thin film, other 2 thin film layer is not affected, can choose the shape of line 3, less waste, high reliability tags: food packaging bags easy tear food sack difficult to tear apart
