Plastic Bag With Filler Masterbatch Aug 21, 2017

Plastic bag with filler masterbatch

Plastic bag is a kind of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as produce, powders, magazines, chemicals, and waste. It is a common form packaging in our normal life.

Bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE, etc.) is the most common. Other forms, including laminates and co-extrusions can be used when the physical properties are needed.

Plastic bags usually use less material than comparable to boxes, cartons, or jars, thus are often considered as "reduced or minimized packaging".

Depending on the construction, plastic bags can be well suited for plastic recycling. They can be incinerated in appropriate facilities for waste-to-energy conversion. They are stable and benign in sanitary landfills.

From the mid-1980s onwards, plastic bags became common for carrying daily groceries from the store to vehicles and homes throughout the developed world. As plastic bags increasingly replaced paper bags, and as other plastic materials and products replaced glass, metal, stone, timber and other materials, a packaging materials war erupted, with plastic shopping bags at the center of highly publicized disputes.

Under the influence of environment protection,ultrathin plastic bag have been forbidden. Such as in India, government has banned use of plastic bags below 50microns.

Although ban plastic bag is a trend, but plastic bag is irreplaceable in the long future. The thicker bag means need more material, means higher production cost. How to reduce the cost is the biggest problem. Filler masterbatch is the best answer. 

Filler masterbatch contain different filler, such as Na2SO4, Ba2SO4, CaCO3, Talc etc. It will reduce the production cost effectively and do not influence the plastic bag properties. The thicker thickness, the higher adding ratio.

And the filler masterbatch also can be widely used in the blowing molding, injection molding, tube, sheet etc.
