Description

TECHNICAL FIELD A making method of buffer for packing made from foamed polyethylene sheet and equipment thereof

The present invention relates to a method and apparatus for manufacturing a foamed polyethylene packaging cushioning material, and more particularly, when the product is boxed, it is assembled with the product and accommodated in the packaging box without any gap, thereby supporting the product without flow in the packaging box. A plurality of assembly members in the manufacturing process for the packaging cushioning material produced by joining a plurality of assembly members produced by flex processing to have a foamed polyethylene sheet that prevents the product from being damaged due to the required shape. The present invention relates to a method of manufacturing a foamed polyethylene packaging cushioning material and an apparatus for producing a packaging cushioning material that meets the manufacturing requirements that change from time to time to multi-kind, small-scale production or small-scale production, and mass production by allowing fast and accurate bonding.

In general, products that are prone to be damaged by an external force are stored and transported by box packaging after being accommodated in a packaging box without flow using a complete packaging material.

This foamed polyethylene packaging cushioning material is manufactured using a foamed polyethylene sheet. That is, a foamed polyethylene sheet is fabricated by joining a plurality of assembly members produced through a flex process to have a required shape to have a structure capable of assembling with the product, thereby fabricating a foamed polyethylene packaging cushioning material. At this time, since foamed polyethylene does not have an adhesive, a thermal bonding method is used in which the bonding surface of the assembly member is melted and bonded with heat.

In the manufacturing process of the foamed polyethylene packaging cushioning material, in the conventional thermal bonding method, the operator uses a heater means to manually heat the stacked assembly member on the base assembly member corresponding to the main body of the plurality of assembly members. The bonding surface of each laminated assembly member is melted using a heating means such as a dryer, and then fused onto the base assembly member to produce a packaging cushioning material.

The conventional manufacturing method of the foamed polyethylene packaging cushioning material did not find any prior art.
