Description

Technical Field

[0001] This utility model relates to the field of label technology, and in particular to an anti-bubble PET beverage bottle label. Background Technology

[0002] PET beverage bottle labels use PET film as the base material. A printed layer is applied to the surface of the base material to display the label content. An adhesive layer is placed beneath the base material to firmly attach the label to the bottle. A release paper layer is placed below the adhesive layer to protect it from contamination and damage during storage and transportation. However, existing PET beverage bottle labels still have the following drawbacks in practical use: 1. When used in high-temperature environments, the air in the adhesive layer expands, creating internal pressure that can lift the label, causing it to loosen and fall off. Furthermore, due to the differences in the thermal expansion coefficients of the various label layers, significant internal stress can occur due to thermal expansion, easily causing the label edges to curl up and affecting the adhesion. 2. Existing labels have poor tear resistance and stain resistance; they are easily torn, and surface stains are difficult to remove. Utility Model Content

[0003] The purpose of this invention is to provide an anti-bubble PET beverage bottle label to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-bubble PET beverage bottle label, comprising a rubber layer, an adhesive layer, and a backing paper. The lower surface of the rubber layer has multiple protrusions evenly distributed, and receiving grooves are formed on the protrusions. The adhesive layer is disposed in the receiving grooves. The backing paper is adhered and fixed to the lower surface of the adhesive layer. A tear-resistant frame is sleeved on the rubber layer. An elastic frame is provided at the top of the tear-resistant frame. A first adhesive layer is adhered and fixed to the upper surface of the rubber layer, and the first adhesive layer is adhered and fixed to the upper surface of the elastic frame.

[0005] Preferably, the inner wall of the receiving groove is provided with a rough surface.

[0006] Preferably, the rubber layer has multiple ventilation holes evenly distributed on it.

[0007] Preferably, the rubber layer has a first groove and a tear-resistant frame is disposed in the first groove, and the rubber layer has a second groove and an elastic frame is disposed in the second groove.

[0008] Preferably, a heat insulation layer is adhered and fixed to the upper surface of the first adhesive layer, and a second adhesive layer is adhered and fixed to the upper surface of the heat insulation layer.

[0022] Working Principle: In this invention, the rubber layer 1 is ventilated through the gaps between the bosses 11 and the ventilation holes 14. The ventilation holes 14 are used for ventilation and heat dissipation. The bosses 11 accommodate the self-adhesive layer 2 through the receiving groove 12. The air bubbles that expand when the self-adhesive layer 2 is heated are directly discharged through the gaps between the bosses 11. The self-adhesive layer 2 is used to stick the label to the object. The rough surface 13 in the receiving groove 12 can enhance the adhesion of the self-adhesive layer 2 and improve the adhesion firmness. The backing paper 3 is used to protect the self-adhesive layer 2. The backing paper 3 needs to be removed before using the label. The rubber layer 1 accommodates the tear-resistant frame 17 through the first groove 15 and the elastic frame 18 through the second groove 16. The tear-resistant frame 17 is made of a high-toughness material, such as PET, to improve the tear resistance of the label. The elastic frame 18 is made of an elastic material, such as a highly elastic metal material. The elastic frame 18 is initially bent towards the rubber layer 1 to counteract the internal stress caused by the thermal expansion of the label. The first adhesive layer 19 connects the heat insulation layer 110 and the elastic frame 18, and also connects the heat insulation layer 110 and the rubber layer 1. The heat insulation layer 110 blocks heat transfer. The second adhesive layer 111 connects the heat insulation layer 110 and the protective frame 4, and also connects the heat insulation layer 110 and the printing layer 42. The protective frame 4 protects the printing layer 42 and the ink layer 43, preventing the absorbent printing layer 42 from getting damp. The protective frame 4 accommodates the printing layer 42 through the third groove 41. The printing layer 42 is used to carry the ink layer 43, which contains the printed label content. The third adhesive layer 44 is used to connect the ink layer 43 and the protective layer 5, which protects the ink layer 43. The hydrophobic coating 51 is used to improve the label's resistance to dirt and facilitate the removal of stains from the label surface. The hydrophobic coating 51 can be a coating with low surface energy, such as a polytetrafluoroethylene coating. The first adhesive layer 19, the second adhesive layer 111, and the third adhesive layer 44 are made of thermosetting adhesives.
