Abstract
The invention provides a heat-sealing type tea filter paper, which comprises an upper heat-sealing layer and a lower heat-sealing layer, the upper heat-sealing layer comprises broad leaf wood pulp fiber and 25%-55% of polypropylene fiber, the lower heat-sealing layer comprises broad leaf wood pulp fiber and 15-45% of polyethylene fiber, and the upper heat-sealing layer and the lower heat-sealing layer are compounded to make the paper. The heat-sealing type tea filter paper has good heat-sealing strength, the making technology is simple, and the heat-sealing type tea filter paper accords with a healthy and economic principle.
Description
Technical field
The present invention relates to pulp technology for making paper, be specifically related to a kind of heat-sealing type tea filter paper.
Background technology
Tea filter paper, is the very common a kind of filter paper of the modern life, is mainly used in making tea bag and cartridge bag.
Tea filter paper is divided into heat-sealing type tea filter paper and non-heat-sealing type tea filter paper, and non-heat-sealing type tea filter paper often needs coating technique, can use multiple additives and adhesive, can affect user's health, and increases cost of manufacture.Progressively pursuing the present of healthy and environmental protection, traditional non-heat-sealing type filter paper obviously cannot meet people's requirement.
Summary of the invention
The object of the invention is the tea filter paper for a kind of economy, health are provided.
In order to achieve the above object, the invention provides following technical scheme: a kind of heat-sealing type tea filter paper, comprise hot sealing layer and lower hot sealing layer, described upper hot sealing layer comprises the polypropylene fibre of hardwood pulp fiber and 25% ~ 55%, described lower hot sealing layer comprises hardwood pulp fiber and 15% ~ 45% polyethylene fiber, described upper hot sealing layer and the compound copy paper of lower hot sealing layer.
Described upper hot sealing layer comprises 30% ~ 50% polypropylene fibre, and described lower hot sealing layer comprises 20% ~ 40% polyethylene fiber.
The heat-sealing temperature that needs two-layer hot sealing layer in the present invention is different, and we adopt polypropylene fibre at upper hot sealing layer, descend hot sealing layer to adopt the more polyethylene fiber of low melting point, and we also can adopt the composite of polypropylene and polyethylene fiber certainly.
The polypropylene fibre addition of upper hot sealing layer is 25% ~ 55%, can affect heat seal strength because heat-sealing type fibrous material addition is too low, causes sealing unsuccessfully; And heat-sealing type fibrous material addition is too high, when heat-sealing type fibrous material is heated after hot melt, filter paper stopwatch has the hole of appearance, and sealing declines, just need to improve the quantitative of paper in order to reduce the appearance in hole, the quantitative increase of paper can progressively cause the decline of Filter paper filtering ability.
Lower hot sealing layer is less demanding for heat seal strength, therefore adopts the polyethylene fiber material of hot melting temperature lower than polypropylene fibre material, and addition also can be lower, and in guarantee, hot sealing layer and lower hot sealing layer can be bonding smoothly.
Beneficial effect of the present invention: because manufacture craft is simple, material environment friendly is pollution-free, and the good stability of finished product filter paper, the therefore good market prospects of tea filter paper of the present invention, economic worth is high, meets the demand of mainstream market.
Detailed description of the invention
Below in conjunction with embodiment, heat-sealing type tea filter paper of the present invention is further described.
