Embodiment Construction

[0017] As shown in Figure 1 is a schematic diagram 4 of an aluminum foil bag applied to a heating bag; the cross-sectional view of the aluminum foil bag body material shown in Figure 2, the aluminum foil material is composed of OPP20-25μm / VMPET12μm / LLDPE25-30μm composite. Surface layer material 1 adopts OPP as shown in Figure 2, inner layer material 3 adopts LLDPE, and in VMPET2, there is a coating between the aluminum plating layer and PET. Ventilation holes can be distributed on the aluminum foil material.

[0018] The bag body material of the aluminum foil bag is cut as required, and heat-sealed to make various packaging materials for heating bags.

[0019] The provided aluminum foil material not only has the characteristics of environmental protection and beauty, but also can improve thermal conductivity, enhance mechanical strength and wear resistance. Used as a packaging material for heating bags, such as warming bags, baby warmers, convenient bosom heaters, heating bag...

Abstract

The invention relates to an application of aluminum foil material in warming bag. The aluminum foil material is compounded by OPP, VMPET and LLDPE. In the VMPET, there is a coating layer between aluminized coating and PET. Air holes are distributed on the aluminum foil material. In the aluminum foil material, a coating is coated on the surface of aluminized coating PET film at first and vacuum aluminum is carried out again. In this way, the coating between aluminized coating and PED film takes an effect of buffer layer so as to decrease the damage to aluminized layer. The aluminized coating is provided with environmental protection and beauty. It can also improve conductivity of heat energy and enhance mechanical strength and wear resistance. The invention, as packaging material, is applied in warming bag. It is provided with high conductivity, high barrier, high strength and energy saving so on, which car not possessed by ordinary packaging material of warming bag.

Description

technical field [0001] The invention relates to a material application, in particular to an application of an aluminum foil material on a heating bag. Background technique [0002] Heating bag, also known as warm bag, warm baby, convenient bosom heater, heating bag, hot bag, etc., has excellent functions of expelling wind and cold and supporting health care. Provide warmth protection for the human body in winter. The heating bag is safe and reliable to use, simple to use, quick to generate heat, long-lasting heating time, stable heating temperature, non-toxic, non-polluting, and easy to carry. It is the best and convenient heating product necessary for winter. [0003] Currently widely used heating bags include portable chemical heating bags, automatic heating bags and hot water bags. Currently, the packaging materials used in heating bags, such as polypropylene, ethylene-vinyl acetate resin film, etc., have low mechanical strength and poor wear resistance. , The barrier p...
