Description

Technical Field

[0001] This utility model relates to the field of flame retardant technology, specifically a flame retardant packaging bag. Background Technology

[0002] The technological development of flame-retardant packaging bags stemmed from the urgent need for safe transportation of flammable goods. Early methods involved interrupting chain reactions using halogenated flame retardants, but this posed a risk of environmental pollution. Later, flame-retardant packaging bags broke during transportation, resulting in the loss of their flame-retardant effect.

[0003] This invention features a food-grade coating that replaces fluorinated compounds, solving the problem of bioaccumulated toxicity. The use of recycled materials reduces the carbon footprint. The five-layer design of the bag makes it flame-retardant and less prone to damage, while the side reinforcements make it more robust. The bottom surface is also protected by a puncture-resistant padding layer, making it less susceptible to damage. Utility Model Content

[0004] The purpose of this utility model is to provide a flame-retardant packaging bag to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant packaging bag, comprising a bag body, wherein the bag body is provided with the following layers from the outside to the inside: an outer flame-retardant layer coated with an intumescent flame retardant; a first substrate layer made of woven polypropylene material; a buffer layer with an internal honeycomb structure; a second substrate layer made of high-temperature resistant polyethylene film; and an inner heat-resistant lining with an anti-slip texture on the surface.

[0006] As a further embodiment of this utility model: the opening end of the bag body is provided with a main sealing zipper.

[0007] As a further improvement of this utility model, the opening end of the bag body is provided with an auxiliary self-adhesive strip.

[0008] As a further improvement of this utility model, the two sides of the bag body are integrally formed with reinforcing ribs.

[0009] As a further improvement of this utility model, the bottom of the bag is provided with a puncture-resistant padding layer.

[0010] As a further improvement of this utility model, the top of the bag is symmetrically provided with adjustable carrying straps.

[0011] Compared with existing technologies, the beneficial effects of this invention are: the food-grade coating replaces fluorinated compounds, solving the problem of bioaccumulation toxicity, and the application of recycled materials reduces the carbon footprint. The five-layer design of the bag makes it flame-retardant and less prone to damage, the side reinforcing ribs make it more robust, and the bottom surface is further protected by a puncture-resistant padding layer, making it less prone to damage.
