Heavy-duty form-fill-seal (FFS) Packaging, or FFS packaging for short, is a plastic film used for heavy-duty packaging, which usually has high mechanical strength, puncture resistance, and good sealing performance. This kind of packaging film is widely used in industrial products, construction materials, agricultural supplies, food packaging, and other fields, such as rice bags, laundry detergent bags, and so on.
Heavy-duty FFS packaging originated in the 1990s, at first it was a single-layer film structure, with LDPE as the main raw material, and to achieve the corresponding mechanical strength, the thickness of the film was up to 200μm.
By the end of the 1990s, the three-layer blown film equipment had become widely popular, especially with the emergence of linear polyethylene, and the thickness of the heavy-duty packaging film had been reduced to 160~180μm.
New materials continue to market, especially the emergence of mLLDPE, more metallocene polyethylene was added to the heavy-duty packaging film formulations, greatly improving the mechanical properties of the film, so that the heavy-duty packaging film in the direction of thinner development. In Europe and the United States, the thickness of three-layer heavy-duty packaging film down to about 120μm, to a large extent, reduces the packaging of raw materials and energy consumption.
However, with the addition of metallocenes, which also cause processing problems, such as seriously affecting the processing fluidity of the resin and reducing productivity, manufacturers usually add fluorinated polymer PPA processing aids to improve the processing fluidity and so on. However, with the strengthening of environmental awareness and the proposal of the EU Fluoride Restriction Directive, the search for alternatives to fluorinated PPA processing aids has become the focus of the industry.
SILIKE PFAS-Free PPA Processing Aids: The Ideal Solution for Replacing Fluorinated PPAs
SILIMER series fluorine-free PPA masterbatch is a PFAS-free polymer processing aid (PPA) developed by SILIKE. Such as SILIMER series PFAS-free PPA masterbatch SILIMER 9100, SILIMER 9200, SILIMER 9300, etc, adding a small amount can effectively improve resin fluidity, lubricity, and surface properties during plastic extrusion, eliminate melt fracture（sharkskin）, reduce friction coefficient, extend equipment cleaning cycle, increase output and quality, and is environmentally friendly and safe. It is an alternative to fluorine-based PPA processing aids.
Typical Benefits:
Improve processability;
Increase extrusion rate;
Eliminate melt fracture（sharkskin);
Reduce die build-up;
PFAS-free and environmentally friendly.
Applications:
SILIMER series PFAS-free PPA masterbatch has a wide range of applications, suitable for mPE, mPP, plastic films, wires and cables, pipes, polyolefin material granulation, color masterbatch, functional masterbatch, artificial grass, monofilament fiber, petrochemical, and chemical industries.
