Dual-layer sealing bag for storing hot melt coating

Abstract

The invention provides a dual-layer sealing bag for storing hot melt coating. The dual-layer sealing bag comprises an external bag and an internal bag in the external bag, the external bag is internally provided with an external bag body, a damp-proof decoration layer is closely glued to the outer layer of the external bag body through a first glue layer, an aluminum foil layer is glued to the inner layer of the external bag body through a second glue layer, and a sponge layer is arranged on the inner surface of the aluminum foil layer. According to the dual-layer sealing bag for storing the hot melt coating, the external bag is provided with the papery damp-proof decoration layer, so that the damp-proof aim can be achieved when the whole external bag is reversely placed; the inner layer is provided with the aluminum foil layer with the sponge layer, the heat-insulation effect can be achieved, and the influence of the external environment on the quality of the hot melt coating is reduced. A sealing strip is arranged on the internal bag, a high sealing effect can be achieved, storage of the hot melt coating is facilitated, and the rain-proof and damp-proof aims can be achieved. A bending section is arranged on the internal bag, the drop-resistant effect can be achieved, and the situation is avoided that under violent impact, the sealing strip in the internal bag is pulled out, and the sealing effect is affected.

Description

technical field [0001] The invention relates to a sealed bag, in particular to a double-layer sealed bag for storing hot-melt paint. Background technique [0002] Hot-melt marking paint is a kind of paint that is applied on the road to mark road markings. Road markings are a kind of safety marking, and even an invisible "language" in road traffic. The hot-melt reflective marking paint is mainly used on roads and expressways above grade 2. The thickness of the marking coating drawn by this paint is (1.0-2.5) mm, and the paint is mixed with reflective glass beads. During line construction, sprinkle reflective glass beads on the surface. This kind of marking has good reflective performance at night and has a long service life. According to the estimation of the demand for various road marking paints in the construction of large roads with traffic flow, it depends on the quality of the paint itself, generally up to (2~ 3 years. The application of hot melt coatings requires s...
