Description

A kind of wrapping paper with antibiotic property

Technical field

The present invention relates to paper and make field, particularly relate to a kind of wrapping paper with antibiotic property.

Background technology

Paper and paperboard is the leading material in packaging material always, accounts for more than 40% of packaging material used.But, traditional paper and paperboard tensile strength and folding strength low, be easy to occur being destroyed by packaging article, cause transport to carry out smoothly, and general wrapping paper do not have antibiotic property, cannot extend the freshness date of food.

Summary of the invention

The object of this invention is to provide a kind of wrapping paper with antibiotic property.

The present invention is achieved through the following technical solutions:

There is a wrapping paper for antibiotic property, be made up of following composition by weight, 30 parts, bamboo powder, corn husks 120 parts, granatum 10 parts, 5 parts, ginger, 8 parts, mulberry leaf, pyruvic acid 4 parts, polyvinyl alcohol 4 parts; It is made up of following making step:

1) corn husks is adopted after clear water cleans, put into after 40% acetum soaks 8-10 hour, pick up nature and dry, be crushed to 200 orders;

2) by granatum, the mulberry leaf sodium bicarbonate solution boiling after 1.5-2 hour of 65%, 200 orders are crushed to;

3) ginger is squeezed into juice, remove residue, stay ginger juice stand-by;

4) by bamboo powder and 1), 2) in made raw material mix after carry out physics making beating, beater is tentatively pulled an oar with 1500r/min speed, and the time is 1.5-2 hour, then carries out secondary making beating with the speed of 2800r/min, and the time is 2-2.5 hour;

5) centrifuging treatment is carried out to paper pulp, decontamination, obtain high concentration paper pulp;

6) again to pull an oar process to high concentration paper pulp with beater, beater rotating speed is 1000r/min, and the time is 3-3.5 hour, and the ratio by weight 2:1 adds pyruvic acid, ginger squeezing juice and polyvinyl alcohol, uniform stirring 0.5-1 hour;

7) by 6) Raw utilizes paper machine to be copied into page, and dewaters, then squeeze, removing 75% ~ 85% moisture content, then carry out drying and processing, the temperature of oven dry is set to 30 DEG C ~ 35 DEG C, and drying time is 2.3 hours;

8) paper of oven dry is carried out cutting, arrangement, packing, storage, namely obtain finished product packing paper.The invention has the beneficial effects as follows, compared with prior art:

1, the present invention possess raw material extensively, reaction temperature and, the advantage such as asepsis environment-protecting, meet the theory of " Green Chemistry " of modern requirements.

2, the present invention make wrapping paper tensile strength and folding strength high, be applicable to the wrapping paper of various occasion.

3, the wrapping paper printing adaptability of the present invention's making is high, deflection good, decreases the consumption to timber, is conducive to the protection of environment and resources.

4, the paper that the present invention makes has high anti-bacterial refreshing, is applicable to food fresh keeping packaging, greatly can improves fresh-keeping degree and the freshness date of food.

Detailed description of the invention

There is a wrapping paper for antibiotic property, be made up of following composition by weight, 30 parts, bamboo powder, corn husks 120 parts, granatum 10 parts, 5 parts, ginger, 8 parts, mulberry leaf, pyruvic acid 4 parts, polyvinyl alcohol 4 parts; It is made up of following making step:

1) corn husks is adopted after clear water cleans, put into after 40% acetum soaks 8-10 hour, pick up nature and dry, be crushed to 200 orders;

2) by granatum, the mulberry leaf sodium bicarbonate solution boiling after 1.5-2 hour of 65%, 200 orders are crushed to;

3) ginger is squeezed into juice, remove residue, stay ginger juice stand-by;

4) by bamboo powder and 1), 2) in made raw material mix after carry out physics making beating, beater is tentatively pulled an oar with 1500r/min speed, and the time is 1.5-2 hour, then carries out secondary making beating with the speed of 2800r/min, and the time is 2-2.5 hour;

5) centrifuging treatment is carried out to paper pulp, decontamination, obtain high concentration paper pulp;

6) again to pull an oar process to high concentration paper pulp with beater, beater rotating speed is 1000r/min, and the time is 3-3.5 hour, and the ratio by weight 2:1 adds pyruvic acid, ginger squeezing juice and polyvinyl alcohol, uniform stirring 0.5-1 hour;

7) by 6) Raw utilizes paper machine to be copied into page, and dewaters, then squeeze, removing 75% ~ 85% moisture content, then carry out drying and processing, the temperature of oven dry is set to 30 DEG C ~ 35 DEG C, and drying time is 2.3 hours;

8) paper of oven dry is carried out cutting, arrangement, packing, storage, namely obtain finished product packing paper.By test comparison wrapping paper of the present invention and general wrapping paper: method of testing and the test condition of two kinds of paper are consistent,

	Tensile strength kgf/15mm	Tearability/g	Folding strength/time
				Wrapping paper of the present invention	2.4	30	9
General wrapping paper	1.3	20	5

Table 1

Wrapping paper of the present invention can be found out than existing wrapping paper in tensile strength by table 1, the performance in tearability and folding strength has obvious advantage.
