Q1: Why do we need different kinds of plastics?
A:Copper,silver and aluminum are all metals, yet each has unique properties. We do not make a car out of silver or a beer can out of copper because the properties of these metals are not the best choice for final product. Likewise, while plastics are all related, each resin has attributes that make it best suited to a particular application. Plastics make this possible because as a material family they are so versatile.
Q2: What's your product range?
Our Main products are Stand Up Zip Lock Bag,Die Cut Shopping Bag,Header Bag,Aluminium Foil Bag,Food Packaging Bag,Printed Packaging Film.Our products are all LEAD/AZO/CADMIUM free.
Q3: How do you ship the finished products?
-By DHL, TNT, FEDEX, UPS, etc.
Q4: How are plastics made?
A: Most commercial plastics encountered by consumers consist of building blocks of carbon. Those building blocks are typically derived from petroleum or natural gas, but can be derived from coal or biological sources. The building blocks of small molecules are called monomers. The monomers used are many and can be combined in various combinations to achieve special properties and characteristics. The nature of the polymer science is such that the monomers must be very pure to make useful plastics. Plastics can be made at very high pressures using gases, in solvents or liquid emulsions, or as melted materials. Each plastic has preferred manufacturing techniques based on its specific chemistry. All successful chemical syntheses are characterized by purification of raw materials, reuse of surplus material, efficient conversion of materials to useful plastic, efficient use of energy, and minimized releases of byproducts to the environment.
