One of the most crucial plastic fillers is filler masterbatch, also known as calcium carbonate filler. It is composed of plastic resins, certain additives, and calcium carbonate (CaCO3), which accounts for more than 70% of the total weight. Because CaCO3 is more useful than plastic resin, it can be applied to plastic combinations to minimize the amount of resin needed, which lowers production costs for plastic businesses. Additionally, calcium carbonate adds several advantages to finished goods, including a reduction in the product's cycle time (caCO3 has a high heat conductivity) and an improvement in the product's mechanical qualities (impact strength, tear resistance, etc.). Because of this, filler masterbatch is frequently utilized in a variety of packaging-related applications, including roll bags, shopping bags, garbage bags, and wrapping films.
The question is, why is it necessary to determine which kinds of calcium carbonate fillers are suitable? Because every product has a unique set of technical specifications, only specific kinds of filler masterbatch that are compatible can fulfill those requirements. Because it could lead to a decline in the quality of the final product, it is therefore very dangerous for plastics companies to choose any kind of filler masterbatch at random for packaging. Thus, what kind of masterbatch should be used as a filler in the packaging industry?
2. Typical Filler Masterbatch for Packaging
2.1. PE Filler Masterbatch for Packaging
PE (polyethylene), CaCO3, and additional additives are used to make PE filler masterbatch. Due to its appropriate mechanical qualities, which include high ductility, impact strength, and low friction, it is a well-known addition to the packaging industry, particularly in blown films.
Lower production costs translate into lower final product costs when calcium carbonate PE filler is used. PE masterbatch filler is frequently used in blown films for items like trash bags, shopping bags, and T-shirt bags. They are often called nylon bags. Moreover, poly films, multi-layer films, PP woven bags, and other products are made using calcium carbonate PE filler.

The qualities of Filler Masterbatch for Packaging are as follows:
Transparent, glossy, flexible, soft, and resistant to moisture as well as waterproof.
PE packaging has poor resistance against O2, CO2, N2, and grease.
Popular PE packaging types, like vacuum PE bags, adhesive PE bags, antistatic PE bags, and transparent PE bags, can be made by mixing PE plastic with functional masterbatches.
2.2. PP Filler Masterbatch for Packaging
Polypropylene resin, CaCO3, and other additives make up the PP filler masterbatch, as the name implies. It is somewhat harder and more heat resistant than polyethylene, but otherwise, its qualities are similar. As a result, PP filler masterbatch is frequently used in PP woven sacks and nonwoven products to reduce manufacturing costs and the negative environmental effects of the process. Packaging made from PP masterbatch has many excellent qualities and is reasonably priced. It can be used in a variety of agricultural and chemical industries, including the packaging of fertilizers, seeds, chemicals, food, and animal feed.

PP Filler Masterbatch for Packaging features the following traits:
PP plastic bags are strong, resilient, and non-stretchable. Although PP filler masterbatch can be turned into fibers, it has the drawback of being easily ripped, so care must be taken when using this product for packaging and shipping.
Because PP bags are either opaque or transparent white, printing logos and images on their surface is simple.
Packaging made of PP plastic is greaseproof and waterproof.
3. Considerations for selecting filler masterbatch for packaging
To determine which Filler Masterbatch for Packaging is best suited for plastic products, you should think about the following questions:
What is the finished product? There are specific technical requirements for each type of product that are only met by a limited number of calcium carbonate fillers. Because of this, the filler masterbatch that is added needs to work with the final products.
What kind of resin is utilized? Because different carriers have different processing temperatures, as we all know, it would be disastrous if your embedded material had a lower melting point than your resins.
How thick is the film you use for packaging? You must inform your supplier of the thickness of your film. If it must be thick, then the filler masterbatch usage rate should be higher than the thinner one, which is typically between 15 and 35%. The film gets thicker the more calcium carbonate filler is applied.
How clear is the layer of your film? More calcium carbonate filler should be used if the film layer needs to be extremely transparent, and vice versa. Plastic companies should use calcium carbonate filler carefully because it lessens the transparency of final products. Transparent filler may work well in some circumstances as an expedient to increase the degree of brightness and transparency.
