Film and Plastic Bags Shredder

Film and plastic bag shredders are specially designed for shredding flexible, easily tangled, low-density plastic films (such as PE/PP films, greenhouse films, and packaging films) and various types of plastic bags (such as shopping bags, express bags, and garbage bags). Their core function is to break loose, easily clumping flexible materials into uniform small pieces or fragments through a shear-tear process, paving the way for subsequent processing steps such as recycling and pelletizing, incineration reduction, and landfill reduction.

Film and plastic bag shredders are primarily suitable for flexible, thin polymer plastic materials, encompassing three main categories:

First, films such as PE heat shrink film, PVC stretch film, BOPP food packaging film, PET vacuum film, as well as agricultural greenhouse film, industrial bubble film, and film production scraps;

Second, plastic bags such as PE vest shopping bags, food storage bags, chemical raw material lining bags, and aluminum-plastic composite bags (requires separable materials);

Third, similar soft plastics such as PE dust covers, pearl cotton foam film, PP strapping tape, and plastic tying twine.

Key Technical Features of Film and Plastic Bag Shredders (Solving the Pain Points of Flexible Material Shredding)

The flexible, easily tangled, and low-density characteristics of film and plastic bags place extremely high demands on the shredder’s design. Therefore, the equipment must possess the following targeted technical features:

1. Anti-tangling Blade Design:

– The core blade utilizes a combination of a “wolf-tooth-shaped moving blade” and staggered fixed blades. The sharp, spirally arranged moving blades quickly tear film while also “peeling” tangled material off the blade shaft through counter-rotation, preventing jamming.

– The blade shaft is made of high-carbon steel (such as 40Cr) with a nitrided surface, achieving a hardness of HRC55 or higher. It is wear-resistant and resists deformation, with a service life of 2-5 years (blades are replaced based on processing volume). 2. Forced Feeding and Compaction:

– Medium-sized and larger models are equipped with a hydraulic pusher plate, which uses hydraulic power to compact loose film/plastic bags into “lumps” before feeding them into the crushing chamber, solving the problem of “difficulty gripping low-density materials and low crushing efficiency.”

– The inner wall of the feed hopper is coated with a low-friction coating (such as nylon) to prevent film from sticking to the hopper and ensure smooth feeding.

3. Sealing and Environmentally Friendly Design:

– The crushing chamber utilizes a fully sealed structure to minimize film fragments and dust leakage during the crushing process.

– Large models are equipped with a bag filter or electrostatic dust collector to capture trace plastic dust generated during crushing, meeting environmental emission requirements.

– Some models feature a noise-reducing housing, keeping operating noise below 75 decibels (medium-sized models), reducing noise pollution to the surrounding environment. 4.

Versatile Adaptability:

– Multi-material Compatible Shredding: In addition to films and plastic bags, it can also shred soft plastics (such as PVC film and bubble wrap) and paper packaging (such as the cushioning paper in courier bags), eliminating the need for frequent tool changes.

– Adjustable Crushing Size: By changing the bottom screen to different apertures (e.g., 5mm, 10mm, 20mm), the crusher can meet the needs of subsequent granulation (for fine particle size) or landfill/incineration (for coarse particle size).
