Plastic inner trays were once standard for food gift boxes, baked goods and fragile snack packaging, used to secure products and cushion impacts. However, the massive use of plastic inner trays has created severe environmental pressure. As plastic restriction policies advance and brands meet their plastic reduction targets, paper alternatives such as molded pulp trays and folded cardboard trays are gaining popularity rapidly, which also puts forward higher requirements for the positioning accuracy and flexible control of cartoning equipment. Horizontal food cartoning machines have become key equipment enabling this transition.
Compared with plastic inner trays, paper inner trays have larger dimensional tolerances, are more brittle and offer less impact resistance. The rigid pushing and rough positioning of traditional cartoning machines can easily cause paper tray fragmentation and product misalignment. Horizontal food cartoning machines upgrade their photoelectric positioning systems and flexible pushing mechanisms to precisely control the position and force of inner tray feeding and product loading. The pushing process applies force evenly to avoid paper tray cracking caused by excessive local pressure, while ensuring accurate product placement in the paper tray so that products do not shift or collide during transportation.
For multi-category food production, the size adjustment capability of horizontal food cartoning machines can fully adapt to paper inner trays of different specifications. Our equipment supports independent adjustment of length, width and height for both cartons and inner trays. By adjusting conveying rails, positioning stops and pushing strokes, it can quickly switch between paper inner trays of different sizes and structures without additional custom fixtures. Whether it is multi-compartment paper trays for mooncake gift boxes, cushion paper trays for baked goods or cardboard trays for snacks, it can be adapted quickly.
Shifting from plastic inner trays to paper alternatives not only reduces plastic usage in packaging, but also better aligns with consumers' green consumption preferences. The adaptability of horizontal food cartoning machines allows food enterprises to smoothly complete their plastic reduction upgrade without sacrificing packaging efficiency or product protection performance.
