Description

Plastic-coated RFID plastic bottle structure capable of improving wrinkles or wrinkles on surface of container label

Technical Field

The utility model relates to a can improve RFID plastic bottle structure is moulded to package of container label surface fold or wrinkle belongs to electronic tags technical field.

Background

RFID, i.e. radio frequency identification, RFID antennas are formed by conductor circuits, and are used as media for RFID signal and energy transmission, and the most popular structure is PET and aluminum foil circuits thereon. The radio frequency tag is an element which is configured between a chip and an RFID antenna by a layer of anisotropic conductive adhesive, has a complete electronic function after being bound by high temperature and high pressure, and comprises a PET substrate, an aluminum foil antenna circuit, the chip and the conductive adhesive.

In the conventional plastic container for packaging food, medicine, cosmetics, cleaning products, nutriment, health product and health product, if RFID function is added, two methods are usually used, one is to stick an RFID tag on the bottle, and the other is to inject a radio frequency tag into the plastic and appearance tag in the bottle.

The way of attaching the RFID tag still has the following problems: the label is easy to be taken off by heating and repeatedly pasted on a counterfeit product, 2 the label has poor concealment, and 3 the label is pasted on a container after the product manufacturing process and packaging are finished, so that the tracing depth is still insufficient, and the data history in production is difficult to trace.

The radio frequency label is injected into the plastic in the bottle and the appearance label mainly by using an IML technology, namely, the conventional radio frequency label is adhered to the inner side (the printing surface of the outer label is defined as the outer side) of the appearance label, the combined label is fixed on the inner side of the female mold, the outer side of the female mold is tightly attached to the female mold, then the plastic is injected or blown between the male mold and the female mold by the male mold, and then the container provided with the preprinted outer label, the RFID layer and the body plastic is formed by demolding. The biggest problem with this design is that the outer label is very prone to wrinkling or wrinkling. Because the PET substrate of the radio frequency identification tag is thick and rigid, the thermal expansion coefficient is smaller than that of PE or PP of the outer tag and the body plastic, the PET layer is arranged between the outer tag and the body plastic, so that the heat conduction is not smooth during high-temperature shaping, and the bubbles and stress are not easy to be led out during thermoplastic molding, so that the rigidity, the thermal deformation and the shrinkage speed of the three layers of materials are not consistent during cooling shrinkage, the outer tag is layered, the bubbles, the bulge, the fold or the wrinkle is formed, the defective product is formed, and the yield of the finished product is low.
