Vacuum bags leak analysis and solution

Vacuum packing is a lot of food all like adopts the way of packing, vacuum bags leak problem food companies a big problem, is sometimes more difficult to find. Because the vacuum is completed, if the gas leak is not big, vacuum bags will not rebound soon. Today small make up with you about the vacuum bags of the main causes of air leakage and solution. 【 Color bags 】 A, vacuum packaging bags on the cause of leakage are: 1, the material of packaging the puncture resistance is poor. In food processing, if the product will be more sharp or there is a solid material, in process of pumping air into vacuum state, the sharp material would strongly with materials. If material is qualitative the puncture resistance cannot meet the demand, then easy to cause air leakage. Usually this problem may find a flat place, no rules to follow, and fillers are hard. Solution: change the material, according to the production demand of their products, can be set in a special case, do more puncture resistant test. 2, automatic packaging machine with sharp objects. This is due to the equipment in use process, causes such as wear, impact, the sharp objects can easily Pierce packaging bags. Usually this kind of situation, flat areas are the same, there are rules to follow. Solution: to observe the damage position, from the device at the end of the period of screening, removal of sharp objects or replacement parts. Second, vacuum packaging bags pincer-like device leakage reasons: 1, packaging specifications is too small, or too much padding. After completion of this is due to the hot sealing, vacuum, the padding is too much, result in the crack of the seal. Solution: reduce the filling or increase the packaging specifications. 2, the material of bag heat sealing viscous force. Due to the running water production line, heat sealing and is not a long time interval between two process of pumping air into vacuum state, heat sealing viscous force is poor, may pincer-like device rupture occurred in the vacuum. Solution: adjust heat sealing knife according to the material temperature, heat sealing pressure and cooling temperature to obtain the best heat sealing viscous force, the general can consulting suppliers, and record the best Settings. Best case will not be able to solve the problem, if can change the material of heat sealing layer. 3, a foreign body bags pincer-like device. Pincer-like device has a foreign body, intentional heat sealing viscous force and effect, it is easy to cause air leakage phenomenon. This is usually due to equipment have sharp hard object cut rub silk produced film, pincer-like device also can see these filamentous material. Solution: be open bags to see incident ceng position, from the end of a automatic packaging equipment, one by one to remove hard objects or replacement parts. Vacuum bags leak prevention mainly do the following work: product processing should avoid too much hard to create, choose the puncture resistance good hot sealing moisture materials, packaging specifications design can meet the demand of filling volume, each automatic packaging equipment set parameters and rule out before starting the hard thing. 【 Guangdong bags 】 Tags: vacuum packing bag
