Masterbatch is concentrated plastic pellets consisting of carrier resin, plastic fillers, colorants for plastic, and other additives. One of the applications of masterbatch is blowing film. If you are a plastic bag manufacturer or blowing film manufacturer, this is the blog for you.
1. Benefits of using masterbatch for blowing film
Filler Masterbatch has many special features that bring many benefits to plastic products. Here are the advantages of masterbatch for blowing film:
+ Increase productivity: increase efficiency and results by increasing output power with temperature and increasing output volume. Filler masterbatch helps to reduce the degree when the physical ratio of the film is high.
+ Anti-clumping, blocking
+ Using Masterbatch in blowing film helps increase white and brightness for the surface
+ Using Masterbatch in blowing film helps with Anti-slipping
+ Using Masterbatch in blowing film will Improve the printing surface
2. Strong points of StarPoly of masterbatch for blowing film
With over 10 years of experience in producing masterbatch and additives, we guarantee our masterbatch for blowing film.
For popular type: We provide customers with various grades of filler masterbatches which are well known as economy grades. These grades have good dispersion, high toughness, improved elongation, more whiteness, and reduce the cost of the end product. Products of these grades can improve processing and output, printability and whiteness, and gloss
For average type: We provide customers with various grades of filler masterbatches that can enhance the product's character, reduce expense, and save costs at the same time. Depending on the customer’s requirements, the compatibility, properties, and characteristics will be determined.
3. Plastic bags made of masterbatch for blowing film
Filler Masterbatch is great for reducing the production costs of products. For many kinds of products like shopping bags, t-shirt bags, garbage bags, food packaging - pouch bags (middle layer), and industrial liners... manufacturers use HDPE, LDPE, and MDPE polymers in the production. Below are the production parameters that blowing film manufacturers shared with the StarPoly team. We can take them as a reference.
For Garbarge bags and sensitive price segments, they normally use more CaCO3 filler, maybe up to 50%, Black Color Masterbatch.
Promotion, good quality bags: They add less than 20% of Calcium fillers. The color and printing must be perfect and match 100% with our Marquette.
Industrial film and other plastic bags and films: They use 20-30% Filler masterbatch, color, and additives.
4. StarPoly produces masterbatch for blown film
First, we manufacture CaCO3 Filler Masterbatch (Some call it CC or Calcium Granules..). We offer a lot of our PE Filler for our customers in blowing film like your previous company, to save them a lot of production cost. The Filler Masterbatch can also help them to increase the brightness, and opacity, reduce shrinkage, and have anti-blocking and slipping effects in plastic film. It also has been proven to save power consumption for blowing film customers. According to the thickness of the film and customer requirements, StarPoly R&D creates formulas specialized for Plastic Bags, we have from code SE-1 to SE-7 with adding rates even up to 50-70%. The popular codes are SE-3 and SE-5.
Second, we can produce Color Masterbatch with great color fastness and thermal resistance to coloring plastic bags and Film. For example: if you want to produce Yellow plastic bags, you can add 2-5% of our yellow grade YEL-2003, and you will have excellent results.

Last but not least, StarPoly provides functional additives to add value to your blowing film products. Let’s check the additives masterbatch for blowing film below.
Bio-Degradable OXO Additives for our blow film customer: many governments from different countries already requesting that plastic bags have to be disposable and compostable.
UV Stabilization: Masterbatch can incorporate additives like UV stabilizers to protect the film from degradation caused by UV radiation. This is crucial in outdoor applications where the film needs to maintain its properties despite exposure to sunlight.
Antioxidants and Antistatic Agents: Masterbatch can be formulated with additives like antioxidants to enhance the film's resistance to oxidation and degradation over time. Antistatic agents can also be added to reduce static charges on the film's surface, which is especially important in packaging to prevent dust attraction.
Slip and Antiblock Properties: Films often require specific surface properties for handling and processing. Masterbatch can include additives such as slip agents to reduce friction between film layers and anti-block agents to prevent film surfaces from sticking together.
Flame Retardancy: Masterbatch formulations can include flame retardant additives to enhance the fire resistance of the blowing film. This is crucial in applications where fire safety is a concern.
Barrier Properties: Some masterbatch additives can enhance the film's barrier properties, making it more resistant to moisture, oxygen, or other gases. This is valuable in packaging applications where maintaining product freshness is essential.
Customized Properties: Manufacturers can create custom masterbatch formulations to meet specific requirements such as increased strength, enhanced flexibility, or improved printability of the film.
