Abstract
The invention relates to a preparation method for food package separating paper. In present food package, general release paper is prepared after body paper is coated with an anti-sticking material, oil-proof paper is employed to package food individually, food is easy to stick onto the oil-proof paper, and thus oil-proof paper needs to be coated with an anti-sticking material such as silicone oil or the like. The preparation method comprises the following steps: firstly, preparation of a separating agent is carried out, the separating agent comprises silicone oil, a catalyst and an organic solvent special for food, the catalyst is a noble metal catalyst, and the organic solvent special for food is No.6 solvent naphtha or edible aromatic hydrocarbon; secondly, oil-proof paper is coated with the separating agent, the coating amount of the separating agent is 0.3-0.6g/m<2>; thirdly, drying of separating paper is carried out, namely, the coated separating paper is dried through a drying tunnel or a drying oven, the drying temperature is 70 DEG C-100 DEG C, the drying air quantity is 7000-9000m<3>/h, the drying time is 15s-30s, and the food package separating paper can be obtained.
Description
technical field:
the present invention relates to a kind of food packaging release paper and preparation method.
background technology:
release liners general in current packaging for foodstuff makes by being coated with preventing viscosity substance on base stock, and described base stock is generally greaseproof paper, and described preventing viscosity substance is generally silicone oil.The fiber bonds of greaseproof paper itself is many, and the porosity of page is low, and transparency is high, infiltration and the absorption of grease can be prevented, be widely used in food liner, scorch, microwave, packaging for foodstuff and the machining field such as freezing.But use greaseproof paper packaged food separately, food is easily bonded on greaseproof paper, therefore need silicon-coating wet goods preventing viscosity substance on greaseproof paper.Silicone oil is because its nontoxic, tasteless, not volatile characteristic, and the surface being usually used in being coated on food wrapper forms adherent layer.And silicone oil has remarkable high-low temperature resistant characteristic, anti-oxidant, good insulating, corrosion-free to metal, thus this type of release liners be specially adapted to as scorching, microwave, the Food processing such as freezing time packaging cushion.
summary of the invention:
the object of this invention is to provide a kind of food packaging release paper and preparation method.
above-mentioned object is realized by following technical scheme:
a preparation method for food packaging release paper, the method comprises the steps:
(1) preparation of release agent: described release agent comprises the special organic solvent of silicone oil, catalyst and food, described catalyst is noble metal catalyst, and the special organic solvent of described food is No. 6 solvent naphthas or edible aromatic hydrocarbon;
(2) on greaseproof paper, be coated with release agent, the coating weight of described release agent is 0.3g-0.6g/m2;
(3) drying of separation papers: by coated separation papers by drying tunnel or oven for drying, bake out temperature is 70 DEG C-100 DEG C, and oven dry air quantity is 7000-9000m3/ hour, and drying time is 15s-30s, can obtain food packaging release paper of the present invention.
the preparation method of described food packaging release paper, described silicone oil parts by weight are 5-15, and described catalyst weight number is 0.02-0.14, and the weight fraction of the special organic solvent of described food is 10-70.
the preparation method of described food packaging release paper, described silicone oil parts by weight are 5, and described catalyst weight number is 0.02, and the weight fraction of the special organic solvent of described food is 10.
the preparation method of described food packaging release paper, described silicone oil parts by weight are 15, and described catalyst weight number is 0.14, and the weight fraction of the special organic solvent of described food is 70.
the preparation method of described food packaging release paper, described silicone oil parts by weight are 10, and described catalyst weight number is 0.08, and the weight fraction of the special organic solvent of described food is 40.
the preparation method of described food packaging release paper, described silicone oil is food-grade silicone oil, and described catalyst is platinum catalyst, palladium catalyst or ruthenium catalyst.
beneficial effect:
1. be easily separated between the food packaging release paper that the present invention superposes mutually, improve efficiency and the quality of packaging for foodstuff; During printing, the strong adhesion of ink on paper, improves printing effect, and the need meeting more various packaging for foodstuff do not increase special operation, concise in technology, and cost is lower.
