Embodiment 1

[0024] 95.99% No. 85 high-grade microcrystalline wax

[0025] 4% Thai YL-300 polyethylene wax

[0026] 0.01% Antioxidant BHT

[0027] Heat and melt the microcrystalline wax, add polyethylene wax and antioxidant, raise the temperature to 140°C, stir at a speed of 60 rpm for about 30 minutes, filter and shape to obtain the product.

Embodiment 2

[0029] 93.99% No. 80 high-grade microcrystalline wax

[0030] 6% Thai YL-100 polyethylene wax

[0031] 0.01% Antioxidant DLTP

[0032] Manufactured by the method described in Example 1, obtained product.

Embodiment 3

[0034] 74% No. 80 high-grade microcrystalline wax

[0035] 3% Korean PE Wax KD-200

[0036] 22.99% No. 62 food grade paraffin wax

[0037] 0.01% Antioxidant BHA

[0038] Manufactured by the method described in Example 1, obtained product. The difference is that food-grade paraffin is added to the formula components.

Abstract

High melting point coating wax and a preparation method thereof are disclosed, belonging to packing material technical filed. The invention takes high grade microcrystal wax as material to prepare high melting point coating wax which is at melting point of 110DEG C and satisfies national food wax standard GB7189-94 through the steps of adding Tissuemat E, high melting point foodstuff paraffin and antioxidant, heating and mixing, filtering and molding. The high melting point coating wax has the advantages of high melting point, good flexibility and good sealing, and is safe to eat and use. The high melting point coating wax can be applied to food packing paper and packing containers which are filled or sealed under high temperature or food packing paper and packing containers which are folding resistant, oil resistant and water vapour penetration resistant, as well as the coating of other wrappages.

Description

technical field [0001] A high melting point coating wax and a preparation method thereof belong to the technical field of packaging materials. The high melting point coating wax can be used for filling, heat sealing at relatively high temperature or for coating of food packaging paper, packaging containers and other packaging materials resistant to folding, oil and water vapor penetration. Background technique [0002] Deeply hydrotreated petroleum waxes (including high-grade microcrystalline wax and food-grade paraffin wax) are highly pure, colorless, and odorless. They have been approved by government food inspection departments and are widely used in food-grade food packaging industries. In order to improve the melting point, hardness and luster of petroleum wax, polyethylene wax, polypropylene and other resin materials are used to modify it, which meets the needs of many purposes. JP 01133056 introduces a transparent electrostatic recording paper with anti-adhesive prop...
