The utility model discloses a waterproof grease proofing heat-seal food package paper's waterproof grease proofing and heat-seal effect drenches the membrane paper with PE and is as free from extraneous, and its temperature resistance performance is between PP and PET, and excellent temperature resistance performance has the food improvement security of temperature for the parcel.
Description
Technical Field
The utility model relates to a food packaging material especially relates to a but replace moulding waterproof grease proofing food package paper of heat-seal with paper.
Background
With the development of the internet platform, the takeaway industry rises up with the internet platform, and disposable products such as lunch boxes, beverage cups, straws, takeaway bags, disposable tableware packaging bags and the like are indispensable. At present, most of known takeout boxes, cups, tubes, bags and the like are made of materials such as PP, PET, PVC and the like, have the characteristics of nondegradable property, difficult recovery and the like, and are easy to cause white pollution to the environment. From the perspective of environmental protection, a degradable, easily recyclable, heat-sealable waterproof and oilproof food wrapping paper is particularly important. Therefore, the development of a heat-sealable waterproof and oilproof food wrapping paper using paper instead of plastic is a problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough, the utility model provides a but replace plastics waterproof grease proofing food package paper of heat-seal with paper.
The above object of the present invention is achieved by the following technical solutions: the utility model provides a but replace moulding waterproof grease proofing food package paper of heat-seal with paper, includes the paper body, paper body one side scribbles waterproof grease proofing layer, and the another side scribbles heat-seal coating.
Further, the waterproof and oilproof coating is an aqueous EAA coating. Ethylene Acrylic Acid (EAA) is a polymer with thermoplasticity and extremely high adhesiveness, and due to the existence of carboxyl groups and the action of hydrogen bonds, crystallization of the polymer is inhibited, and the linearity of a main chain is destroyed, so that the transparency and toughness of the EAA are improved, and the melting point and softening point are reduced.
A preparation method of a plastic-replaced heat-sealable waterproof and oilproof food wrapping paper comprises the following steps of coating thin paper and coating thick paper:
(1) aiming at the problems that the single side of thin paper is easy to curl and deform due to coating, when the thin paper passes through a first feeding anilox roller, the back of the thin paper needs to be coated with a waterproof and oilproof coating, the thin paper is dried at 50 ℃ by an oven at the speed of 25 +/-5 m/min, when the thin paper passes through a second feeding anilox roller, a heat-seal coating is coated in a reverse mode, a wire rod is additionally arranged, the uniformity and the feeding amount of a full-plate coating can be better controlled, the coating precision is improved, and the thin paper is dried at different temperatures of 45 ℃/55 ℃/85 ℃/85 ℃ by a five-section oven in a matching mode, so that the coated surface of the thin paper is uniform in coating, and the problems of curling, tilting and the like do not exist;
(2) aiming at the thick paper, when the single-side coating is carried out, the curling deformation is less, so the back coating step is omitted, the single-side reverse coating waterproof and oilproof heat-sealing coating is carried out twice, and the five-section oven is matched and dried at different temperatures of 40 +/-5 meters per minute and 90 ℃/100 ℃/110 ℃/110 ℃; a wire rod is additionally arranged in the reverse coating process (the wire rod is a metering tool), so that the uniformity of full-plate coating and the feeding precision are improved.
Further, the water and oil resistant coating and the heat seal coating both contain an aqueous acrylic emulsion of EAA.
Further, in the step (1), the water-proof and oil-proof coating and the heat-seal coating are diluted by mixing a mixed solution of water and alcohol.
Further, in the step (1), the coating amount per one time is controlled to 5 to 6 g.
Further, in the step (2), the water-proof and oil-proof coating is diluted by adding a mixed solution of water and alcohol.
Further, in the step (3), the coating amount per one time is controlled to 7.5 to 8 g.
Compared with the prior art, the utility model the advantage be: the utility model discloses a waterproof grease proofing heat-seal food wrapping paper is whole to use food level water-based material, and the effect after the making beating is unanimous basically with the body paper making beating. The waterproof, oil-proof and heat-sealing effects are the same as those of PE laminating paper, the temperature resistance of the PE laminating paper is between that of PP and PET, and the excellent temperature resistance improves the safety of food wrapped with temperature, which is incomparable with wax paper, PE paper and oil-proof paper.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the heat-seal waterproof and oil-proof food packaging paper with the plastic replaced by the paper comprises a paper body 1, wherein one side of the paper body 1 is coated with a waterproof and oil-proof layer 2, and the other side of the paper body is coated with a heat-seal coating layer 3.
Further, the waterproof and oilproof coating is an aqueous EAA coating. Ethylene Acrylic Acid (EAA) is a polymer with thermoplasticity and extremely high adhesiveness, and due to the existence of carboxyl groups and the action of hydrogen bonds, crystallization of the polymer is inhibited, and the linearity of a main chain is destroyed, so that the transparency and toughness of the EAA are improved, and the melting point and softening point are reduced.
As shown in fig. 1 and fig. 2, a preparation method of a heat-sealable waterproof and oilproof food packaging paper with paper instead of plastic comprises the following steps of coating thin paper and coating thick paper:
(1) aiming at the problems that the single side of thin paper is easy to curl and deform due to coating, when the thin paper passes through a first feeding anilox roller 4, the back of the thin paper needs to be coated with a waterproof and oilproof coating, the thin paper is dried at 50 ℃ by an oven 7 at the speed of 25 +/-5 m/min, when the thin paper passes through a second feeding anilox roller 5, a heat-seal coating is coated in a reverse mode, a wire rod 6 is additionally arranged, the uniformity and the feeding amount of a full-page coating can be better controlled, the coating precision is improved, and the thin paper is dried at different temperatures of 45 ℃/55 ℃/85 ℃/85 ℃ by a five-section oven in a matching mode, so that the coated surface of the thin paper is uniform in coating, and the problems of curling, warping and the like do not exist;
(2) aiming at the thick paper, when the single-side coating is carried out, the curling deformation is less, so the back coating step is omitted, the single-side reverse coating waterproof and oilproof heat-sealing coating is carried out twice, and the five-section oven is matched and dried at different temperatures of 40 +/-5 meters per minute and 90 ℃/100 ℃/110 ℃/110 ℃; a wire rod is additionally arranged in the reverse coating process (the wire rod is a metering tool), so that the uniformity of full-plate coating and the feeding precision are improved.
Further, in the step (1), the water-proof and oil-proof coating and the heat-seal coating are diluted by mixing a mixed solution of water and alcohol.
