Is usually used in the packing of glass and plastic, these two materials has become the main current packaging materials.
So, glass and plastic what is the difference between these two kinds of raw materials, which is better?
glass is main raw material, packing material its bright transparent, good chemical stability, airtight, not changeful form, will not release harmful material in high temperature. But the glass is easily broken, weight big defect, but overall glass bottles or have a lot of advantages. The density of glass bottles used sodium calcium glass bottles of 2. 5 - 2. 6 g/cm3, brittleness is big, low thermal conductivity. With metal ions, colorant can be made into green, dark green, shallow blue, amber glass.
the advantages of glass packaging container:
1, good chemical stability, non-toxic, tasteless, clean health, had no any bad effect on packaging.
2, barrier property good, can provide good quality conditions.
3, good transparency, built-in objects are visible.
4, good rigidity, not easy to deformation.
5, forming good workability, can be processed into a variety of shapes.
6, good temperature tolerance, high temperature sterilization, can also be stored at low temperature.
7, abundant raw materials, recycled repeated use, no pollution to the environment.
and plastic packaging container is USES the high polymer synthetic materials, can be made into all kinds of form, often used in hospitals, plastic bags, plastic bottles, etc.
the advantages of plastic packaging containers:
1, good mechanics performance, light weight, convenient transportation, easy to carry.
2, the permeability resistance, good sealing, high transparency.
3, processing performance is good, can be made into all kinds of the size of the bottle, cap, thin films, bags and composite packaging materials.
4, decorative coloring and printing performance is good. Drug identification, specification, and shown to sign, bar code can be directly inkjet or printed on the plastic material, and will not fall off.
5, good chemical stability, toxicity, health and safety. The lid of the drug can make insurance cover or pressure cover, and anti-counterfeiting mark and so on.
this is the difference between the two, but overall, they much better than plastic, is currently the most widely used a kind of raw materials.
