The Lindner Washtech Sheet & Boxes | Big Bags System Solution is a modular and fully engineered recycling process developed for rigid and semi-rigid plastic packaging, including sheets, thermoformed trays, crates, boxes and FIBC big bags. These materials typically consist of PP, HDPE or mixed polyolefin structures and require targeted processing due to their geometry, wall thickness and contamination profile.
The system combines shredding, washing, separation and drying technologies to deliver clean, homogeneous flakes suitable for extrusion, compounding and new packaging production.
Sheets & Thermoformed Boxes
This category includes plastic sheets, trays and thermoformed packaging, commonly used in food logistics, retail and industrial packaging.
Typical challenge: multilayer structures, surface contamination, labels and residual product.
System objective: precise size reduction followed by intensive washing and density-based separation to remove incompatible materials and contaminants.
Result: clean flakes with stable physical properties, ideal for sheet extrusion and thermoforming applications.
Plastic Crates & Boxes
Rigid crates and boxes used in logistics, agriculture and industrial transport.
Typical challenge: thick-walled materials with possible metal inserts, labels or mixed polymers.
System objective: efficient shredding and separation to isolate the target polymer while protecting downstream equipment.
Result: durable recycled material suitable for injection molding or industrial packaging reuse.
FIBC / Big Bags
Flexible Intermediate Bulk Containers (Big Bags) used for transporting bulk materials such as chemicals, food ingredients or construction materials.
Typical challenge: high-strength woven PP structure, contamination from contents and dust.
System objective: robust shredding combined with effective washing and separation to remove residues and foreign materials.
Result: high-quality PP recyclate ready for compounding or durable plastic applications.
Why the Sheet & Boxes | Big Bags Solution is Strategic
These packaging formats represent a significant recyclable resource but require specialized treatment due to their size, structure and contamination characteristics. The Washtech solution provides a balanced mechanical and washing process tailored to rigid and woven packaging materials.
Main Operational Benefits
In Summary — Sheet & Boxes | Big Bags System Solution
