The materials properties of composite bags have?

The invariance of the 1, a) Machinability of composite packaging materials tensile strength, elongation and other targets of film supplier and use are the main, tear strength experiment practice on primary measurement ripped hyperplasia, needed for the first measurement method have breeches and Mr Lai's door ripped method, optimization of constant radius sample to Mr Madoff pull door to break the law. Tear force is too large for film processors may be too small to manufacturing process can are in danger. For consumers, the tear resistance function of materials is related to packaging can easy open sealable a prime target. In practice in the process of the packing of the friction is often drag force and resistance, friction coefficient of intrusive and therefore must be useful restraint, to make it within proper limits. Active packaging coil, general requirements inner compare with small friction coefficient, and the outer friction coefficient is moderate. Material thickness can average consensus about the various functions of the target material also has a major impact. b) Heat sealing bag sealing, bonding sex is the composite packing a order at the end of the process. Heat sealing bag making requires excellent heat sealing fastness, can accept the pocket after processing and disposal without leakage. Compactness of the seal with the accurate choice of heat sealing materials, heat sealing pressure, heat sealing temperature and time and heat sealing method has a lot to do. c) Printing compliance, abrasion resistance, adhesion, accuracy and so on several target first is according to the characteristics of the printing industry is put forward. 2, mechanical maintenance of composite packaging may be a small package, application of sealing apparatus can detect the package after through a series of imitating experiment ( As shaking experiment, drop test, compression, etc. ) The sealing function. Is a color printing, bag of plastic flexible packaging has a large-scale production enterprises, focus on product development, design, production in one of the one-stop service. Depth at the same time committed to industrial upgrading strategy, successively introduced five new automatic high-speed printing machines, 2 sets of solventless laminating machine and bag making equipment. With 'new, fast, realistic and optimal' work style to win customer satisfaction.
