Abstract
The invention discloses an antibacterial plastic shopping bag material which is characterized in that raw materials of the antibacterial plastic shopping bag material comprise the following ingredients, by weight, 70-80 parts of linear low density polyethylene, 20-30 parts of vinyl alcohol copoyhner barrier resin, 6-8 parts of titanium dioxide plastic masterbatch, 0.6-0.8 part of composite antibacterial, 5-7 parts of tourmaline negative ion powder, 1.2-1.5 parts of polypropylene grafted carboxylic acid and 2-4 parts of polyethylene wax. According to the invention, by adding linear low density polyethylene and tourmaline negative ion powder with the function of emitting negative ions into plastic to prepare the product with an antibacterial function and make the product generate synergetic effects, antibacterial activity of titanium dioxide can be excited and the product is endowed with a negative ion function and has strong effects of inhibiting bacteria, killing bacteria and resisting mildew. The product can clean the air, resist bacteria and eliminate peculiar smell.
Description
Technical field
The invention belongs to the technical field of Plastic Packaging Materials, be specifically related to a kind of antibiotic plastic shopping bag material.
Background technology
Linear low density polyethylene film heat sealability is good, as long as reach the minimum envelope temperature that rises just have good heat seal strength, sealing contamination resistance is strong.The melting tension force of LLDPE is low, and the time of relaxation of melting stress is short.Can observe from " T " and type head extrude to melt film necking down large, during slush molding, the drawdown degree of parison is large.Because melting stress relaxation time is short, in injection-molded article, residual stress is little, and therefore shrinking percentage is little, and warpage is also little.The heat sealability of film is corresponding to the heat-sealing temperature melted completely, and LLDPE heat-sealing temperature is than LDPE height 10-15 degree Celsius, and LLDPE is narrower than LDPE melting range, so the heat sealability of film is good.Tensile property and the LDPE ratio of LLDPE, stretching quantity, tensile yield strength are large, and physical and mechanical properties is obviously better than LDPE, its flexibility, toughness, and winter hardiness, paracentesis resistance is all better than LDPE.
Tourmaline anion powder has excellent antibiotic and sterilizing function, because the negative oxygen ion produced in anion powder has higher activity, there is very strong redoxomorphism, the cytolemma of bacterium or the activity of cellular plasm organized enzyme can be destroyed, thus reach the object of antibiotic and sterilizing.Negative ion in anion powder in atmosphere movement presents " Z " font.And conveying negative charge is to bacterium, dust, smoke particles and water droplet etc., this particulate of electric charge and this combines and is polymerized to ball and sinks, thus reaches the object purified air.
Along with social progress, medicine, healthcare products, foods prods are on the increase, the packing material of the product particularly health of plastic shopping bag and safety more and more causes the concern of consumers in general, plastic shopping bag take polyolefine as main raw material, suitably adds other material and the wrapping material made.In order to reduce its cost, most of enterprise all adds about 30% calcium carbonate and makes filled plastics shopping bag, and this type of plastic shopping bag is not because giving off poisonous gas when burning in refuse tip.Antibiotic plastic refers to and adds antiseptic-germicide in the plastic, make plastics itself have germ resistance, can within a certain period of time the bacterium of staiing on plastics be killed or suppress, compare with physical method with the chemistry of routine, use antibiotic plastic sterilization timeliness long, not only economy but also facilitate.
The development and application of antibiotic plastic has set up one green screen for protecting human health, and for improving environment for human survival, reduce disease, protection fitness-for-all, tool is of great significance.Because antibiotic plastic can fundamentally reduce or avoid person to person, people and thing, the cross infection of bacterium between thing and thing, the plastics with antibacterial are generally subject to people's attention and welcome.
Summary of the invention
The object of the present invention is to provide a kind of antibiotic plastic shopping bag material, improve the germ resistance of plastic shopping bag, there is the effect of potent anti-bacteria, kill bacteria and mildew-resistant.
The technical scheme that the present invention takes is:
A kind of antibiotic plastic shopping bag material, it is characterized in that, feed components is composed as follows according to weight fraction:
LLDPE 70-80 part, ethylene-vinyl alcohol copolymer barrier resins 20-30 part, titanium dioxide plastic master batch 6-8 part, complex antimicrobials 0.6-0.8 part, tourmaline anion powder 5-7 part, polypropylene grafted carboxylic acid 1.2-1.5 part, polyethylene wax 2-4 part.
The ethylene content of above-mentioned ethylene-vinyl alcohol copolymer barrier resins is 40-50%, and moisture controlled is 0.4%.
Above-mentioned complex antimicrobials is the mixture that chitosan, nano phase ag_2 o and poly (hexamethylene) acid sodium forms according to weight ratio 1:4:20-23.
Beneficial effect of the present invention is:
LLDPE and the tourmaline anion powder with transmitting anion function are added in plastics to make and are had antibacterial goods by the present invention, it is made to produce synergistic function, the anti-microbial activity of titanium dioxide can be excited, goods are made to have anion function, there is the effect of potent anti-bacteria, kill bacteria and mildew-resistant, energy fresh air, antibacterial elimination peculiar smell.
