Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, in particular to an XPE and EPE composite high-strength packaging structure. Background Art

[0002] EPE, or expanded polyethylene, is a new type of high-strength waterproof material with good cushioning and thermal insulation properties. It forms an independent closed-cell structure during the manufacturing process, which gives it significant advantages in waterproofing and moisture-proofing. XPE, the full name of which is cross-linked polyethylene foam material, is widely used for its good adhesive properties and stable thermal insulation effect. However, compared with EPE materials, its performance in high strength and durability is slightly insufficient.

[0003] Advantages of EPE: Its excellent tensile strength and cushioning properties make it widely used in shockproof and packaging fields; in addition, due to its high waterproof and moisture-proof properties and high durability, it is also often used in the construction industry; at the same time, EPE is environmentally friendly and non-toxic, and harmless to the human body.

[0004] Disadvantages of XPE: Although XPE performs well in thermal insulation, it is relatively weak in high strength and durability. Performance is prone to degradation after long-term use or in harsh environments. In addition, XPE's waterproof performance in certain application scenarios may be inferior to EPE. In order to further improve the performance of packaging materials, the two materials are generally composited.

[0005] The existing document with announcement number CN209321628U discloses a combination cushioning packaging box, which includes a bottom plate, a tray, and an inner filling layer. The tray is buckled on the bottom plate to form a filling cavity between the tray and the bottom plate, and the filling cavity is filled with the inner filling layer. The inner filling layer includes a first inner filling layer arranged to fit the bottom plate and a second inner filling layer arranged to fit the tray. The first inner filling layer and the second inner filling layer are made of any two materials selected from EPE, EVA, PU, ​​and XPE / IXPE respectively. The tray is a blister tray made of any one material selected from ABS, HIPS, PMMA, PVC, PC, PP, HDPE, PETG, PET, and ABS / PMMA.

[0006] The existing cushioning packaging base is generally selected and used according to actual use. Its specifications and sizes are fixed. The cushioning packaging base is placed at the bottom of the packaging box. If the cushioning packaging base is not compatible with the bottom of the box, either a cushioning packaging base of another specification is replaced, or supplementary parts are added to fill the bottom of the box with the cushioning packaging base. This is not only troublesome to operate, but also in actual use, due to the lack of corresponding connection between the filled supplementary parts and the cushioning packaging base, the stability is insufficient, which has a negative impact on the overall cushioning packaging effect.

[0007] To this end, the utility model proposes an XPE and EPE composite high-strength packaging structure to solve the above problems. Utility Model Content
