The utility model discloses an adsorptive environmental protection oil absorption recovery bag, including recovery bag main part, and recovery bag main part carries out the wrapping to tubular product, and recovery bag main part is multilayer structure, and recovery bag main part includes buffer layer, oil absorption layer, anti -infiltration layer, inner protective layer and outer layer from inside to outside in proper order, the material of outer layer of the utility model resists external impact in the use process, ensures that packing bag still can keep physical performance and chemical stability under the severe environment, adapts the severe working condition in the turnover process. Buffer layer plays the buffer effect of tubular product and oil absorption bag, avoids the damage of physical impact in the operation process to other functional materials. Oil absorption layer has the characteristics of oil absorption, and adsorbs and locks the oiliness in the mixture. Anti -infiltration layer has the barrier property, prevents the seepage of oil -water mixture. Inner protective layer relieves the destruction of internal tubular product to recovery bag main part. The whole impact resistance is strong, safe and durable, is not easy to be corroded, is obviously superior to traditional plastic cloth wrapping mode, is suitable for popularization and application.

The invention relates to a preparation method of a biomass composite reinforced circulating corrugated carton, and belongs to the technical field of environment-friendly packaging materials. Uniformly mixing bamboo pulp and enzyme modified bamboo pulp fibers, firstly performing ultrasonic treatment, then introducing saturated steam for treatment, and filtering to obtain a pretreated raw material; sequentially carrying out biological bleaching and non-oxidizing bleaching on the pretreated raw materials, adding natural beewax emulsion for modification, immersing the pretreated raw materials into a chitosan solution, and filtering to obtain composite reinforced fibers; dispersing the composite reinforced fibers in deionized water to prepare paper pulp, and respectively preparing surface paper, corrugating medium paper and inner paper through papermaking, wet pressing molding and hot air drying; and uniformly coating the modified starch-based adhesive on the bonding surface, drying and cutting to obtain the corrugated carton. The corrugated carton prepared by the invention can be completely biodegraded within 5 months, and is excellent in environmental protection performance; the tensile strength and the bursting strength are improved; the water contact angle is large, the water resistance is obviously improved, and transportation in a humid environment can be adapted.
