Description

Combination folded pulp mold liner

technical field

The invention relates to a cushioning liner, in particular to a folded pulp mold liner which is suitable for large flat liquid crystal display packaging and can play a role of cushioning and protection between the packaged object and the outer packaging carton.

Background technique

Usually when the product is packaged, a cushioning pad is used between the product and the outer packaging to ensure the safety of the product during storage and transportation.

Traditional cushioning pads usually use chemical products such as expanded polystyrene (EPS). Packaging engineering practice has proved that cushioning packaging made of EPS materials can provide sufficient protection for large flat-panel liquid crystal displays. Chinese patent CN101372277A discloses a main frame body composed of foamed polyethylene material with two different densities and a reinforcing rib cushion to protect packaged products. However, the buffer packaging of chemical materials is difficult to recycle, and it is difficult to degrade in nature. Extensive use and disposal will cause huge pollution to the environment. Under the current trend of pursuing low-carbon and recyclable utilization, the industry has gradually banned the use of difficult-to-degrade chemical packaging materials.

Pulp molds use waste paper and pulp as raw materials, which are environmentally friendly and can be recycled, making them a good substitute for chemical cushion materials. Research on the cushioning mechanism and performance of pulp molded structures has always been valued by the field of mechanics and packaging engineering, and a large number of related theoretical research literatures have been published [Research on cushioning performance and reliability of pulp molded packaging structures, Zhang Yepeng, 2007, Wuhan University of Technology University Doctoral Dissertation].

Pulp mold liner uses the deformation of its own structure to absorb the kinetic energy of the packaged product during transportation to achieve the purpose of protecting the product. For light weight and small packaged products, the paper mold cushion liner is made after a series of processes Pads have been used in packaging engineering. Due to the nonlinearity of the pulp material and the difficulties caused by the large deformation of the pulp mold structure, the design of the paper mold liner structure that provides cushioning protection for electronic products such as large-weight and large-size liquid crystal displays has become a problem that needs to be solved.

Contents of the invention

The main purpose of the present invention is to overcome the defects of the original EPS packaging, use recyclable and environmentally friendly pulp materials, have good cushioning performance, and provide sufficient protection for the corners, edges, and surfaces that are most likely to cause damage to the side and bottom Corner side face combination folded pulp mold liner.

To achieve the above object, the present invention adopts the following technical solutions:

Combining folded pulp mold pads with corners, sides and surfaces, with 4 side pads with the same structure and 4 corner pads with the same structure; the 4 side pads and the 4 corner pads form an integrated rectangular frame symmetrical structure;

The side pads have a U-shaped structure, and the inner surfaces on both sides of the side pads are provided with protruding heads at intervals, and the inner bottom surface of the side pads is provided with convex strips with symmetrical slots at intervals, and each convex head is symmetrically arranged in the slots of the convex strips ; The corner pad is a right-angle structure, the inner surfaces of the two right-angle sides of the corner pad are provided with interlocking falcon head structures, and the adjacent side pads are connected by the corner pad.

Compared with the prior art, the present invention has the following outstanding advantages:

1. It can completely cover the edge of the product (such as a large flat liquid crystal display) and provide buffer protection for the product.

2. The size of the liner can be adjusted according to the size of the product, and it can be applied to the packaging protection of various types of displays;

3. It can meet the different protection requirements of product corners, edges and surfaces, and can provide sufficient protection for the side and bottom edges that are most likely to be damaged when the product is dropped.
