[Sovereign Items] 1. A method of using a stretch hood film to externally package palletized containers, characterized in that the goods are regularly stacked on a pallet, and the palletized containers are transported to a stretch film packaging machine. , 30-300μm thick polyethylene stretch film film roll is placed on top of the tray, and four uniformly distributed grippers grip the four corners of the stretch hood film and heat-sealed with a hot knife. Cut into a bag with an opening facing downwards. The gripper stretches the film outwards. After the size exceeds the tray assembly, the gripper pulls the film from the top of the tray to the bottom of the tray. After the tray is below the height, the gripper releases the film. When the stretch hood rebounds, the tray body can be packaged as a whole.

[Abstract] The present invention discloses a method for external packaging of a tray assembly using a stretch hood film. The goods are regularly stacked on a pallet, and then the pallet assembly is delivered to a stretch film packaging machine. A polyethylene stretch film with a thickness of 30-300 μm is rolled over the tray, and a stretch film packaging machine is used. The evenly distributed grippers grip the four corners of the stretch hood film, heat-seal them with a hot knife, and cut them into an open-ended bag. The gripper stretches the film outwards. After the size exceeds the pallet volume, the gripper Pull the film from the top of the tray to the bottom of the tray. Below the height of the tray, the gripper releases the film and the stretch hood springs back, and the tray pack can be packaged as a whole. The invention has strong wrapping force, the packaged product is crisp, easy to stack, does not loose during transportation, has strong protection, can prevent rain, water pouring, and the package is beautiful.
