[0008] The inner surface of both ends of the tubular body is covered with a coating layer, and the coating layer is made of an environmentally friendly polymer material that becomes sticky after heating;

[0009] The two end coating layers are melted and bonded by heating and pressing to form a heat-sealed end portion without adhesive, achieving sealing.

[0010] As a further scheme of the utility model, the material of the coating layer is selected from one of polylactic acid (PLA), polyethylene (PE) or starch-based composite material.

[0011] As a further scheme of the utility model, the heating temperature of the heat-sealed end portion is 140-180℃, and the pressing time is 0.5-3 seconds to form a seamless linear seal.

[0012] As a further scheme of the utility model, the diameter to length ratio of the tubular body is 1:5 to 1:20, which is suitable for packaging stick candy, nuts or granular food.

[0013] As a further scheme of the present utility model, the inner side of the heat-sealed end part is pre-provided with a food-grade desiccant layer, and the desiccant layer is fixed by a lamination material heat sealing.

[0014] As a further scheme of the present utility model, the outer surface of the tubular body is coated with a waterproof coating, and the waterproof coating is a water-based acrylic resin or a silicone material.

[0015] Compared with the prior art, the embodiments of the present utility model have the following beneficial effects:

[0016] The degradable paper-based material and the environment-friendly lamination layer (such as PLA and starch-based material) are adopted to avoid the use of traditional plastic packaging and chemical adhesive, meet the green packaging trend, reduce the environmental pollution risk, and ensure the safety of direct contact with food because the lamination material is food-grade;

[0017] The sealing is realized by directly activating the adhesion of the lamination layers at both ends through heating and pressurization, the traditional adhesive coating process is omitted, the production process is simplified, the equipment and raw material costs are reduced, and the packaging efficiency is significantly improved;

[0018] The heat-sealed end part forms a seamless linear seal, avoids the air leakage or seepage problem caused by uneven adhesive, and has high sealing reliability; the waterproof coating and the built-in food-grade desiccant layer can further prolong the shelf life and adapt to the storage conditions of different foods such as candies and nuts;

[0019] The tubular body has a diameter-to-length ratio suitable for rod-shaped or granular foods, is convenient for carrying and quantitative use, and has strong market applicability.
