Background technique

When packaging home appliances, it is generally necessary to set a foam board at the bottom and upper part of the product to play the role of shockproof and support to ensure the safety of the product during transportation. The foam board is easy to break due to its soft material. Generally, the packaging is packaged in the form of a combination of foam and cardboard, that is, a layer of cardboard is placed on the bottom of the foam board to prevent the foam board from being damaged. Due to the poor moisture, water and abrasion resistance of the paperboard, it is difficult to protect the foam board and the product. Once it is wet or seepage, the cardboard will be damaged immediately. Therefore, it is necessary to develop a kind of New packaging pad. In order to reduce the weight of the foam board and save material, a plurality of holes are generally provided at the bottom of the foam board, which is more likely to be broken at the hole position.

detailed description

Referring to Figures 1-2, a foam pad for packaging comprising a foam pad body 1 having a contour of the front side 11 of the foam pad body 1 adapted to the end contour of the product, the foam pad body 1 The back surface 12 is covered with a supporting layer 3, and the supporting layer 3 is covered with a plastic film 2, and the supporting layer 3 and the plastic film 2 are closely adhered to the bottom end surface of the foam board body 1. The support layer 3 is a support net or a kraft paper or a woven cloth or a thin plate, etc., as long as the hole 4 is covered at the bottom of the foam pad and the plastic film is supported, the support layer 3 can only cover the hole 4 and support The length and width of the layer 3 are larger than the size of the hole 4, and the cover form can save the material of the support layer, thereby saving cost; the support layer 3 can also cover the bottom of the entire foam pad, and the full coverage is convenient for laying. The support layer, while its support strength is better and more stable. The support layer of the embodiment is preferably a support mesh, and the material of the support mesh may be a fiber mesh or a steel mesh. The support layer 3 may be attached to the back surface of the foam pad body by gluing or pressing. By providing the support layer, the coverage strength of the plastic film at the hole position can be effectively improved, and the plastic film can be prevented from being damaged at the hole position during use, thereby improving the service life and packaging reliability of the foam pad for the package.

Referring to Figures 2-5, the plastic film 2 and the back surface 12 of the foam board are closely adhered by means of a glue joint or a press fit. The horizontal projection size of the plastic film 2 is larger than the horizontal projection size of the foam pad body 1, and the plastic film 2 is directly aligned with the center of the back surface of the foam pad body 1, and the plastic film 2 is wider than the plastic film 2 A portion of the back surface of the foam pad body 1 is formed with a flange 21 which is bent toward the side surface 13 of the foam pad body 1 and closely adheres to the side surface of the foam pad body 1, plastic film 2 The specific bonding sequence with the foam board body 1 is as shown in FIGS. 3 to 4 to 5 to 2. The plastic film 2 is a PET film (high temperature resistant polyester film) or an OPP film (the OPP protective film is made of OPP (biaxially oriented polypropylene) as a substrate, and the acrylic coating is applied on one side and bonded to the release film. (Plastic film of single layer non-contact release film) or PS film (polystyrene film), of course, other plastic films having similar properties can also be used. In order to overcome the problems of moisture-proof, waterproof and wear-resistant performance of the traditional packaging paperboard, the foam pad for packaging of the utility model is bonded with a foam film by a PET film or an OPP film or a PS film, and the material thickness of the plastic film is Between 0.05mm and 0.25mm, the PET film or OPP film or PS film is compounded with the packaging foam by gluing and pressing, because the mechanical properties of the PET film, OPP film and PS film are good, and the toughness is in the plastic. Best, tensile strength and impact strength are much higher than general packaging materials, better than cardboard performance, dimensional stability, good heat resistance, cold resistance, oil resistance and good chemical resistance, more suitable Protect the product. In addition, since the plastic film of the present invention and the foam pad body are integrally formed by gluing or pressing, the support layer is easy to carry under the support of the support layer, and the foam pad can be effectively prevented from being damaged during the movement. The traditional paperboard and foam board separate packaging design, the foam cushion of the utility model can greatly improve the packaging efficiency and reduce the packaging cost, and the mechanical properties of the PET film, the OPP film and the PS film can be repeated. use.

In this embodiment, the width of the flange 21 is greater than or equal to 5 mm, and the side surface of the foam pad body can be completely covered, and the front surface of the foam pad body can be covered to further improve the waterproof and moistureproof performance. Of course, based on cost and usage habits, the width of the hem is generally 2-5 cm.

Referring to FIG. 6, in order to facilitate folding of the plastic film toward the side surface 13 of the foam pad body, the plastic film 2 is provided with a notch at four corners outside the horizontal projection (the dotted line portion in the figure) of the foam pad body. 22, the specific structural form of the notch 22 is not limited, as long as the folding is convenient.
