Choisir le mélange maître de remplissage pour l'emballage : ce que vous devez savoir

Undeniably, the appearance of Filler masterbatch (or calcium carbonate filler) is increasingly promoting the development of the plastic industry to become the industry of the world. The benefits of filler masterbatch for the plastic industry, in general, have been mentioned quite a bit. The information below refers to the use of CaCO3 filler masterbatch for the packaging industry in particular – one of the largest areas in the plastic industry.

The final products of the packaging industry can be mentioned as shopping bags, wrapping films, roll bags, garbage bags, etc. They all contain the filler masterbatch ingredient but are consumed differently between the end products because of the difference in characteristics and technical requirements of each product. Therefore, it is quite risky for plastic enterprises to randomly select any kind of auxiliary material for the production of packaging because it can reduce the quality of the final product.

Alors quel genre de mélange maître de remplissage l'industrie de l'emballage devrait-elle utiliser ?

Mélange maître de remplissage PE

PE filler masterbatch is made from PE (Polyethylene), CaCO3, and other additives. It is a familiar additive for the packaging industry, especially in blown films due to its suitable mechanical properties such as high ductility, impact strength, and low friction.


Using calcium carbonate PE filler significantly reduces production costs, helping to lower the cost of the final product. Some common applications of PE masterbatch filler in blown films include shopping bags, T-shirt bags, garbage bags, etc. In addition, calcium carbonate PE filler is also used in the production of PP woven bags, poly films, multi-layer films, etc

Mélange maître de remplissage PP

PP filler masterbatch is composed of PP (polypropylene), CaCO3, and other additives. Its properties are similar to those of polyethylene, but a bit stiffer and more heat resistant. Therefore, synthetic PP filler is often used in PP woven sacks and nonwovens to reduce production costs and minimize the environmental impact of the production process.

Mélange maître de remplissage transparent

Another type of filler that can be used in the production of packaging is a transparent filler, which is a combination of BaSO4 (Barium sulfate) or Na2SO4 (Sodium sulfate), plasticizers, and other special additifs. Most plastic manufacturers use transparent fillers to improve some end product properties such as stiffness, mechanical properties (bending strength, impact strength), tear-resistance, and criticality. The most important is whiteness.

Mélange maître de remplissage transparent

Grâce aux deux ingrédients sulfate de baryum et sulfate de sodium, les produits finaux ont une luminosité et une transparence étonnantes. De plus, l'utilisation de charges transparentes réduit le temps requis pour chaque cycle de produit, facilitant ainsi une meilleure efficacité de production. En raison de ces avantages, ce matériau est largement utilisé dans de nombreuses applications telles que les films d'emballage, les conteneurs, les bouteilles, les canettes, etc.

Quels sont les avantages du mélange maître de remplissage CaCO3 dans l’industrie de l’emballage ?

One of the most important plastic fillers is CaCO3 Filler Masterbatch, also known as calcium carbonate filler. It is a blend of calcium carbonate (CaCO3), which accounts for more than 70% of the total weight, plastic resins, and other specific additives. Because CaCO3 is less expensive than plastic resin, incorporating it into a plastic combination reduces the amount of resin required, allowing plastic enterprises to save money on production costs.


Furthermore, calcium carbonate provides numerous benefits to end-products, such as shortening the product’s cycle (due to CaCO3’s high thermal conductivity) and improving the product’s mechanical properties (impact strength, tear resistance, etc.). As a result, filler masterbatch is widely used in a variety of packaging applications such as shopping bags, wrapping films, roll bags, garbage bags, and so on.
