Because of the increase in plastic input materials, the use of CaCO3 filler in the packaging industry has now become more and more popular, especially in the packaging industry. In this article, let’s discover top 5 most common applications of calcium carbonate filler in the packaging industry.
According to some research, packaging industry takes up 39% of the total amount of CaCO3 filler consumed, making it the largest consumer of calcium carbonate. This figure is much greater than the second-largest field, which is building & construction industry with 21%. That statistics implied the popularity of calcium carbonate filler in the packaging industry. So, what applications in particular is this material applied in?
1. Benefits of using CaCO3 filler in the packaging industry?
Calcium carbonate filler is the combination of CaCO3 powder, plastic resins (PP, PE,…) and other additives (normally processing aid and dispersion agent). Thanks to the presence of CaCO3 powder, whose price is relatively lower than that of plastic resins, this material is more affordable and reasonable for plastic enterprises. Besides, CaCO3 filler also assists in improving certain properties of end-products such as mechanical properties, rigidity, thermal resistance,… thus increasing products’ competitiveness.
2. 5 most common uses of CaCO3 filler in the packaging industry
Food wrapping film
Plastic wrap was initially created from polyvinyl chloride (PVC), which is the most common plastic component globally. However, due to many concerns regarding toxic penetration of the film, low-density polyethylene (LDPE) has been chosen as a safer alternative. Though it is less adhesive than PVC, it can be reinforced by adding linear low-density polyethylene (LLDPE), which also improves the film’s tensile strength.
Nevertheless, the revolution hadn’t been really initiated until CaCO3 filler came into use. With a view to saving production cost, PE filler masterbatch is added to partly replace PE resin in the manufacturing process. The usage rate of PE calcium carbonate filler is determined by end-products’ technical requirements, normally varying between 5 to 50% of the total weight. Thanks to the compatibility of PE filler masterbatch to the original plastic combination, it merely cause any chemical changes on the original content, which makes it more appealing to plastic manufacturers.
Furthermore, the application of CaCO3 filler in the packaging industry not only provides customers with a more affordable solution, but also enhances end-products’ properties such as rigidity, flexibility and thermal resistance.
Similar to food wrapping film, the application of CaCO3 filler in roll bags has significantly decreased the production cost as CaCO3 powder is more affordable than plastic resin. Besides, as roll bags are mostly used in food-contact application, the use of calcium carbonate has alleviated negative impacts on consumers’ health which resulted from fossil plastic components.
PE filler masterbatch is the most preferable when it comes to roll bags material thanks to its excellent flexibility, plasticity, waterproof and anti moisture ability. Besides, transparent filler masterbatch with barium sulfate and sodium sulfate as reinforced substances is also used to improve the transparency of end-products.
T-shirt bags/Shopping bags
Another important application of CaCO3 filler in the packaging industry is T-shirt bags and shopping bags. According to some research, the average American family takes home almost 1,500 plastic shopping bags a year, which again proves an increasing demand on plastic shopping bags. The application of PE filler masterbatch not only helps plastic enterprises reduce production cost, but also improves plastic performance by increasing elongation, tear strength and printability.
Nevertheless, the most amazing application of CaCO3 filler in shopping bags manufacturing must definitely be bio filler. This material is the combination of bioplastic and CaCO3 powder, thus allowing end-products to be biodegradable after use, which minimizes the amount of waste released. Besides, bio filler also acts as a processing aid in blown film, which reduces the possibility that film layers get stick to each other, to streamline the manufacturing efficiency.
Woven bags are one of the most important applications of CaCO3 filler in the packaging industry. Basically, input material for woven bags is required to meet certain standards in terms of rigidity, tear strength, printability and price, of course. That leads to the application of polypropylene (PP) filler in woven bags manufacturing. Not only does it offer end-products a competitive price, PP calcium carbonate filler also significantly improves end-products’ mechanical properties such as impact strength, tear strength, printability, thermal resistance,…Thereby, the use of PP filler in woven bags manufacturing largely contributes to the success of plastic enterprises.
Single-use packaging products
For decades, single-use plastic products have been accused of causing severe environmental pollution because of its fossil resins components. However, this no longer bothers plastic manufacturers as the application of bio filler masterbatch has opened up many opportunities for them to cut down on the amount of single-use plastic waste. Thanks to the composition of bioplastic and CaCO3 powder, bio filler is completely biodegradable while maintaining competitive price. Thus, it not only lessens the burden on the waste processing system, but also helps plastic manufacturers save production cost.
Furthermore, bio filler masterbatch also plays as an effective anti-block and slipping agent since it minimizes the stickiness among film layers, thus streamlining the blowing process. As CaCO3 is an efficient thermal conductive, it shortens the amount of time required for the production cycle, which drives efficiency and cost-effectiveness for manufacturers.
