Characteristics And Recognition Methods Of Commonly Used Blister Materials
- Oct 26, 2017 -

Commonly used plastic materials are PS (polystyrene), PP (polyphenylene), PVC (polyvinyl chloride) and APET (non-crystalline - polyethylene terephthalate).


PS is good insulation, easy to color, good ventilation, water resistance, chemical resistance, non-toxic, hard and soft under the greenhouse, high temperature soft, poor solubility, acid and alkali corrosion, but soluble in chloroform, And other organic solvents. PS in the plastic industry is widely used in the material, because of its comprehensive physical properties and easy physical modification, it is widely used, commonly used to make plastic tray, containing fragile electronic components and components.


PP high toughness, good insulation, chemical resistance, light, non-toxic and tasteless, can be 100 ° C boiling water immersion deformation, no damage, common acid-base organic solvent it almost does not work. PP inert and very good, its products durable, without chemical corrosion and resistance to 100 ° C high temperature, can be widely used in turnover tray and food blister.


PVC insulation is good, good transparency, good ventilation, water and corrosion resistance, durable, plastic products can be heat-resistant sealing, but the material process by adding plasticizers and anti-aging agent and some toxic auxiliary materials, Must be toxic. Transparent PVC used in the field of plastic used to create folding or bottom cover sets of plastic box, mainly for electronic products, toys, handicrafts and other packaging, not for food and medicine.



APET toughness and impact resistance, good transparency, good gas barrier, good flavor preservation, good resistance to grease, chemical resistance, the minimum operating temperature of -40 ° C. APET has a high strength, its plastic products used to make products outside the packaging and plastic tray, to protect the impact of small items.
