Description

Technical Field

[0001] This utility model relates to the field of co-extruded film bubble envelope technology, specifically a moisture-proof co-extruded film bubble envelope. Background Technology

[0002] The outer material of bubble envelopes can be customized according to customer requirements: aluminum foil, aluminized film in various colors, anti-static properties, printing of various patterns, and easy-tear strips, etc. They are mainly used for small commodities to provide pressure protection, waterproofing, and shockproofing.

[0003] However, existing co-extruded bubble wrap envelopes are made only of bubble wrap and a custom-made waterproof membrane or other membrane on the outer surface. When in use, the bubble wrap is easily torn and damaged, and it is also easy to exchange with the outside temperature, which can cause the inside of the bag to become damp and contaminate the stored items, thus failing to protect the items.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a moisture-proof co-extruded film bubble envelope. Utility Model Content

[0005] The purpose of this invention is to provide a moisture-proof co-extruded film bubble envelope to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof co-extruded film bubble envelope bag, comprising a bubble bag, a waterproof film fixedly disposed on the outer surface of the bubble bag, a tear-resistant layer adhered and fixedly disposed on the inner surface of the bubble bag, a heat insulation layer fixedly pressed onto the inner surface of the tear-resistant layer, and a foam pad adhered and fixedly disposed on the inner surface of the heat insulation layer.

[0007] Preferably, the waterproof film is a polytetrafluoroethylene film, and the tear-resistant layer is a polyvinyl chloride film.

[0008] Preferably, the insulation layer is polyurethane foam, and the foam pad serves as the inner core of the entire bubble envelope.

[0009] Preferably, the outer surface of the bubble wrap is provided with creases, which are located below the opening of the bubble wrap.

[0010] Preferably, an adhesive sticker is fixedly disposed on the surface of the foam pad, and the surface of the adhesive sticker has an easy-tear film attached when not in use.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a waterproof film, a tear-resistant layer, a thermal insulation layer, and a foam pad. The waterproof film enhances the overall waterproof capability of the bubble bag, while the tear-resistant layer prevents tearing and puncture damage, improving its durability. The thermal insulation layer prevents temperature exchange between the inside and outside of the bag, avoiding moisture buildup caused by temperature fluctuations. The PVC film used in the tear-resistant layer also provides moisture and water resistance, further enhancing the bag's moisture-proof capabilities. The foam pad strengthens the protection of the items stored inside the bag and absorbs any small amount of moisture generated inside, further preventing moisture buildup.

[0013] 2. This utility model, through the setting of creases and adhesive, allows the bubble bag to be easily folded and sealed together at the creases, thus completely sealing the bag opening. With the adhesive securing it in place, the bag opening can be effectively closed, preventing gaps from forming that would allow for the exchange of air between the inside and outside, resulting in internal dampness.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-2 As shown, a moisture-proof co-extruded film bubble envelope bag includes a bubble bag 1, a waterproof film 2 fixedly disposed on the outer surface of the bubble bag 1, a tear-resistant layer 3 adhesively and fixedly disposed on the inner surface of the bubble bag 1, a heat insulation layer 4 fixedly and pressed onto the inner surface of the tear-resistant layer 3, and a foam pad 5 adhesively and fixedly disposed on the inner surface of the heat insulation layer 4.

[0019] Waterproof membrane 2 is a polytetrafluoroethylene membrane, and tear-resistant layer 3 is a polyvinyl chloride membrane;

[0020] The insulation layer 4 is made of polyurethane foam, and the foam pad 5 serves as the inner core of the entire bubble envelope.

[0021] By adopting the above technical solution, the waterproof film 2 can improve the waterproof capability of the entire bubble bag 1;

[0022] The tear-resistant layer 3 can prevent the bubble bag 1 from tearing, breaking or puncturing. At the same time, the tear-resistant layer 3 is made of polyvinyl chloride film, which can also provide moisture and water resistance.

[0023] The insulation layer 4 can prevent temperature exchange between the inside of the bag and the outside, and prevent moisture from appearing inside the bag due to temperature differences.

[0024] The foam pad 5 enhances the protection of items stored inside the bag and absorbs small amounts of moisture generated inside the bag, thus preventing the bag from becoming damp again.

[0025] Furthermore, the outer surface of the bubble bag 1 is provided with creases 6, which are located below the opening of the bubble bag 1.

[0026] By adopting the above technical solution, the bubble bag 1 can be easily folded together at the crease 6 to completely seal the bag opening and prevent gaps from forming, which could lead to air exchange between the inside and outside and cause internal dampness.

[0027] Furthermore, an adhesive sticker 7 is fixedly provided on the surface of the foam pad 5, and an easy-tear film is attached to the surface of the adhesive sticker 7 when it is not in use.

[0028] By adopting the above technical solution, the adhesive tape 7 can fix the folded and closed bag opening.

[0029] Working Principle: When using this moisture-proof co-extruded film bubble envelope, firstly, the items to be stored are placed inside the entire bubble bag 1. The items first come into contact with the soft foam pad 5. The foam pad 5 can enhance the protection of the items stored inside the bag and absorb the small amount of moisture generated inside the bag. After the items are stored, the bubble bag 1 can be easily folded together at the crease 6 to completely seal the bag opening. With the help of the adhesive tape 7, the bag opening can be effectively closed, preventing gaps from causing air exchange between the inside and outside. The entire bubble bag 1 utilizes a waterproof film 2 to enhance its waterproof capability, and the tear-resistant layer 3 can prevent the bubble bag 1 from tearing, breaking, or puncturing, thus improving its durability. The heat insulation layer 4 can prevent temperature exchange between the inside and outside of the bag, avoiding moisture inside the bag caused by temperature differences. At the same time, the tear-resistant layer 3, made of polyvinyl chloride film, can also provide moisture and water resistance, further enhancing the bag's moisture-proof capability. This is the working principle of this moisture-proof co-extruded film bubble envelope.
