[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Referring to Figs. 1-3 A high barrier cold punch forming medicine packaging material structure, comprising an aluminium foil piece 1, the bottom end of the aluminium foil piece 1 is provided with a nylon layer 2, the lower side of the nylon layer 2 is provided with an oriented polypropylene layer 3, the lower side of the oriented polypropylene layer 3 is provided with a heat sealing adhesive layer 4, and the lower side of the heat sealing adhesive layer 4 is provided with a polyethylene terephthalate layer 5.

[0022] The upper end surface of the aluminium foil piece 1 is provided with a plurality of anti-skid bosses 6 at equal intervals, the anti-skid bosses 6 on the upper end surface of the aluminium foil piece 1 can increase the friction force of the packaging surface, facilitate taking and operation, and prevent the package from accidentally falling during transportation or use. Whether in a pharmacy to take medicine or when a patient uses medicine, the anti-skid bosses 6 can provide a better grip.

[0023] The upper end surface of the polyethylene terephthalate layer 5 is provided with a heat preservation groove 7, and the heat preservation groove 7 is filled with heat preservation material.

[0024] Each side of the aluminium foil piece 1 is provided in a round corner, the round corner design reduces the risk of scratching caused by sharp corners during handling, storage and use, and the flexibility of the nylon layer 2 helps the material to adapt to the shape of the mold, which can deform along the contour of the mold during cold stamping, reducing the possibility of cracking and damage.

[0025] The aluminium foil piece 1 provides certain rigidity and shape retention, so that the formed package can maintain a predetermined shape and will not easily deform.

[0026] In use, this invention first uses a cold stamping machine to stamp aluminum foil 1 and nylon layer 2 into shape. Then, the medicine can be placed on the stamped aluminum foil 1 and nylon layer 2. Next, the oriented polypropylene layer 3 can be bonded to the nylon layer 2. Then, the heat-sealing adhesive layer 4 and polyethylene terephthalate layer 5 are bonded together. Aluminum foil 1 has excellent barrier properties, which can block light, oxygen, water vapor, etc., and prevent the medicine from being damp, oxidized, or deteriorated by light. As the main barrier, it can effectively isolate the medicine from external adverse factors.

[0027] The nylon layer 2 has good mechanical properties and certain barrier properties, which can enhance the strength and toughness of the packaging, while also helping to block the influence of external factors on the medicine. The presence of the nylon layer 2 makes the packaging less prone to damage when facing certain external impacts, and further blocks the interference of the external environment on the medicine.

[0028] The oriented polypropylene layer 3 exhibits good water resistance, oil resistance, and chemical stability, further enhancing the barrier properties of the packaging and protecting the medicine from external environmental damage. It works synergistically with the aluminum foil sheet 1 and the nylon layer 2 to provide a stable storage environment for the medicine in all aspects.

[0029] The heat-sealing adhesive layer 4 can achieve sealing under heating and pressure, forming a closed space in the packaging to prevent drug leakage and prevent outside air and impurities from entering the packaging, thus ensuring the quality and stability of the drug. Through the heat-sealing operation, the heat-sealing adhesive layer 4 is tightly bonded to other layers to form a complete and sealed package, ensuring that the drug does not come into contact with the external environment during storage and transportation.

[0030] The oriented polypropylene layer 3 and the polyethylene terephthalate layer 5 also possess excellent processing properties, enabling the material to be smoothly stamped into the required shape, resulting in packaging with good appearance and dimensional accuracy. They work together to ensure smooth processing of the packaging material during cold stamping and the final molding quality.

[0031] The insulation groove 7, located on the upper surface of the polyethylene terephthalate layer 5, is filled with insulation material. This insulation material helps to keep the medicine warm, reducing the impact of external temperature changes. It is particularly suitable for medicines with specific temperature requirements, helping to maintain the medicine within a suitable temperature range and ensuring its quality and efficacy. The insulation material in the insulation groove 7 slows down heat transfer, helping to maintain a relatively stable ambient temperature for the medicine inside the packaging when external temperatures change.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
