Blister technology introduction (2012-05-15)
A plastic processing technology, the main principle is to flat plastic sheet is heated to soften, adopts the vacuum adsorption on the mold surface, after cooling type, widely used in plastic packaging, lamp act the role ofing. Advertising. Decoration and other industries.
Blister packaging products mainly include: blister. Tray. Blister box. Also belong to the said: vacuum hood. Blister, blister packaging equipment mainly package boast: blister forming machine. Punching machine. Sealing machine. The high frequency machine. Choosing machines. Packaging form the packing of the products can be divided into: plugins. Double blister card. Half a blister. Folded blister. Thirty percent 's shell, etc.
Blister process will be transparent plastic plate made specific protuberance of transparent plastic, cover on the surface of the product, protect and beautify the role of products, ordinary plastic plate on the surface of a layer of solute material, making a solute the surface of the tray handle, used to improve the level of packaging products,
Using a special process of modified materials blister tray, the material on the surface of the ohm resistance value is less than 10 of 11 times. IT is mainly used for electricity. IT products electrostatic tray. Blister mold production, lowest cost yes plaster mold, the second is the electroplating of copper, is the most expensive aluminum mold, mold hole is drilled, used for vacuum adsorption thermalization plate, forming blister products.
We often speak of the blister, the softening of blister molding machine will be adsorbed on the surface of mould, plastic plate after cooling, the formation of concave and convex shape of the plastic.
Blister cutting: blister packaging after molding plastic products, after punching machine, the sheet die with the sword of large, can be divided into a single product.
Folding: blister packaging products packing, there is a call plug-ins in the need to use blister three edge folding machine folding to behind, so that the packaging work preface, insert paper card ruffled, form the card packaging.
Thermal sealing: a vacuum encapsulation technology, the surface coated with blister with sealing machine oil paper card with blister and also together, form the suction card packaging,
High-frequency sealing: a vacuum encapsulation in process with high Zhou Boji producing ultrasonic, blister and blister together, forming double blister package is installed, and high frequency sealing the difference is that ultrasound can not only seal PVC, PET, PETG material, also can seal PET material, but also for sealing products has electromagnetism damage, especially suitable for electronics packaging: shortcoming in ultrasonic sealing side only the interval of dot, and and is usually a time front cover side.
1. Blister packaging what are the commonly used plastic sheet?What is the distinguishing feature of each?A: blister packing sheet name plate or film, commonly used are: PET (polyethylene terephthalate oxalic ester) plate, PVC (polyvinyl chloride) plate, PS (polystyrene) plate.Low density of PS plate, poor toughness, easy to burn, styrene combustion would produce gas (harmful gases), and so are commonly used to produce all kinds of industrial blister tray.PVC plate medium toughness, not easy combustion, the combustion can be induced in chlorine gas, a certain effects on the environment, PVC heat sealing, can use sealing side of sealing machine and high frequency machine, is the main raw material production transparent blister products.PET plate good toughness, high transparency, easy burning, burning does not produce harmful gases, belong to the environmental protection material, but the price is high, suitable for high-end blister products, blister blister of European and American countries generally require the use of PET plate, but it is not easy to heat sealing, bring great difficult to encapsulate, in order to solve this problem, people with a call PETG glycol modified - the material of polyethylene terephthalate, this kind of material is both easy to heat sealing of PVC, also has a PET high environmental protection and transparency, but the price higher.
2. What call card packaging?Card packing should be paid attention to what problem?Card packaging refers to the paper card and folded trilateral transparent blister together packaging form, its characteristic is packing don't need any equipment, only need workers will products, blister and paper card put in place.The problem is that should be paid attention to:
1. The paper card and folded edge of the blister size appropriate, too close together, paper card and blister will change;Too loose, it is easy to escape.
2. The product is overweight, should be considered in a certain position paper card with blister is fixed with a staple.
3. What do you mean by suction card packaging?Suction card packaging should pay attention to what problem?Suction card packing is blister MWCNTS in paper card with blister oil table surface, battery packaging use such common supermarket.Its characteristic is to suck encapsulation products packaging equipment to between the paper card with blister.The problem is that should be paid attention to:
1. The paper card surface must have blister oil (to PVC blister with a thermal glued together).
2. The blister can only use PVC or PETG sheet;
3. Because the blister is just stick to the surface of paper card, it is not easy for packaging products is too heavy.
4. What is double blister packing?Double blister packing should be paid attention to what problem?Double blister packaging refers to the paper card with two blister in sealing together with the product packaging forms.Its characteristic is to require high Zhou Boji will double blister sealing side, the efficiency is low, the packing cost is higher, but is neat and beautiful, high-grade product appearance.
