The invention discloses a kind of sterilizing dampproof packaging of tea, including composite inner layer and sealable outer, wherein, composite inner layer, in parts by weight, it is made up of following raw materials according：90 100 parts of ldpe resin, 7 15 parts of type low density polyethylene resin, 14 parts of nano titanium oxide, 25 parts of citric acid, 6 10 parts of bamboo charcoal particle, 24 parts of Sodium Polyacrylate, 35 parts of aerosil, 24 parts of nano-ceramic powder, 24 parts of glycerin monostearate, 12 parts of 24 part, nanometer rubber powder of silicone emulsion, 12 parts of paraffin oil；Sealable outer, in parts by weight, it is made up of following raw materials according：70 85 parts of polyethylene, 30 35 parts of polyurethane.Invention additionally discloses the preparation method of above-mentioned sterilizing dampproof packaging of tea.
Description
Technical field
The present invention relates to processing film field, and in particular to a kind of sterilizing dampproof packaging of tea and preparation method thereof.
Background technology
As people's living standard constantly improves, requirement of the people to tea quality is constantly lifted, promote tealeaves making,
The technique such as packaging and storage continues to develop and lifting.Tealeaves has the characteristic such as the easy moisture absorption, oxidizable, broken, perishable, so
Tea packaging is particularly important.Existing tea packaging takes inside and outside two layers of packaging substantially, and internal layer typically uses vacuum plastic bag bag
Dress, ensure tealeaves lucifuge, keep away oxygen, keep away tide；Outer layer ensures for hard material, prevents tealeaves to be extruded broken, ensures tealeaves form
Completely.At present, most of tea-bag internal layer of in the market takes aluminium foil layer, and the packaging of tea sealing effectiveness of aluminium foil layer is poor,
Cause the anti-microbial property of such packaging of tea poor, so that tealeaves safety effect is poor, the holding time is shorter.
The content of the invention
Can good, holding time length sterilizing dampproof packaging of tea it is an object of the invention to provide a kind of sealing.
In order to achieve the above object, sterilizing dampproof packaging of tea of the invention, including composite inner layer and sealable outer, its
In,
Described composite inner layer, in parts by weight, it is made up of following raw materials according：Ldpe resin 90-100 parts, line
Type ldpe resin 7-15 parts, nano titanium oxide 1-4 parts, citric acid 2-5 parts, bamboo charcoal particle 6-10 parts, polypropylene
Sour sodium 2-4 parts, aerosil 3-5 parts, nano-ceramic powder 2-4 parts, glycerin monostearate 2-4 parts, silicone emulsion 2-4
Part, nanometer rubber powder 1-2 parts, paraffin oil 1-2 parts；
Described sealable outer, in parts by weight, it is made up of following raw materials according：Polyethylene 70-85 parts, polyurethane 30-35 parts.
It is another object of the present invention to provide the preparation method of above-mentioned sterilizing dampproof packaging of tea, including following step
Suddenly：
A takes the ldpe resin of said ratio, type low density polyethylene resin, nano titanium oxide, citric acid, bamboo
Charcoal particle, Sodium Polyacrylate, aerosil, nano-ceramic powder, glycerin monostearate, silicone emulsion, nanometer rubber powder, stone
Wax oil, melted, be kneaded by extrusion or extrusion blow moulding technique, being extruded, being cooled down, being dried, after pelletizing, blown film is produced in compound
Layer；
B takes the polyethylene of said ratio, polyurethane, melted, be kneaded by extrusion or extrusion blow moulding technique, extruded, cooled down,
Dry, after pelletizing, blown film produces sealable outer；
Sterilizing dampproof packaging of tea is made in the outside of composite inner layer plating print sealable outer, then by hot sealing process in c.
The beneficial effects of the invention are as follows：The present invention is aided with ultra-low density polyethylene using low density polyethylene (LDPE) as primary raw material
And packaging of tea internal layer is made in multiple functions auxiliary agent, the internal layer has splendid barrier, can effectively prevent the oxygen in air
Gas and moisture cause tealeaves to be oxidized or go mouldy after being contacted with tealeaves, and have excellent resistance to negative pressure, avoid in vacuum packet
Because damaged intolerant to negative pressure during dress, so as to improve the script mouthfeel for preserving tealeaves.
The embodiment of form by the following examples, the above of the present invention is remake further specifically
It is bright, but the scope that should not be construed as the above-mentioned theme of the present invention is only limitted to following embodiment, it is all to be based on the above institute of the present invention
