Plastic has become a ubiquitous material in modern life. The versatile characteristics of plastics such as easy to handle, resilient, glossy, cheaper and feasibility for mass production make it an ideal choice. Without a doubt, plastic is slowly replacing the paper, metal, glass, wood, and other materials in the market.

Lately, plastics are used almost in every industry around the globe. From the water bottle, soft drinks packaging to the durable car to airplane accessories, everything can be made of plastic these days. Plastic is matchless when it comes to consumer-friendly, cost-effective, sustainable and glossy products.

But, how do plastic get such diverse characteristics and features?

The characteristics of plastic are defined by the use of masterbatch and manufacturing process used at the plant. The diverse color, durability, tensile strength, gloss, resistant to heat and weather are determined during the producing process. In short, the masterbatches and additives play a significant role in shaping the billions dollar plastic industry.

Masterbatch is a solid and liquid additive ...
... added to the plastic to offer color and enhance features in the end product. The MB and additives are added to the carrier resin in different proportion based on the desired outcome on the plastics.

Engineering of quality masterbatches and additives require a lot of research and expertise in the polymer industry. The quality end product is determined by the nature of a masterbatch used in manufacturing. Let us look at the top manufacturing processes where MBs are essential -

Injection molding
blow molding.
Sheet extrusion
Woven sack extrusion
Non-woven extrusion.
Monofilaments.
Pipe extrusion.
Agriculture.
Automotive
Electrical and electronics.
Health and pharmaceuticals.

As we see, there are many benefits of MBs used in various industries. Here we will be discussing the role of masterbatches in the packaging industry -

PET/Polyester masterbatch

Polyethylene Terephthalate is a polymer used in the packaging industry for injection molding. The process helps to maintain transparency, gloss, safety and high-grade plastics to the companies.

With the use of PET/polyester masterbatch, companies can manufacture superior plastic for foods, lightweight bottles, shampoo bottles, color consistency, and other range of applications.   

Here are some of the advantages of using this MB -

Excellent colorfastness
Low dosage required.
Enhanced thermal stability.
Food grade products.
Prevent migration from acting as slippage agent.
Protect from UV.
And others.

PP Woven Masterbatch

Polypropylene is a thermoplastic polymer used in the automotive, textile and food packaging industry. The PP is resistant to chemical solvent.

WOVEN SACK EXTRUSION

The use of PP in the woven sack manufacturing is a norm used in storing and transporting food grains to fertilizer. With the use of Polypropylene non woven masterbatch, the sacks gain features like water-proof, tensile strength and durability necessary to be excellent packaging materials. Apart from that, the MB offers specific benefits such as UV resistance, anti-slip, and others.  

The MB is used in the extrusion process for commercial and industrial uses. Some of the typical applications of woven sacks are agriculture, transportation, building, chemical, and other industries.

Conclusion

The role of masterbatches is undeniable in shaping the packaging industry of PP in the modern market. Companies should select high-grades MB and additives to get the desired outcome in the plastics.
