Abstract
Relating to packaging films, the invention provides an anti-stretching and crease resistant agricultural mulching film. The film is characterized by comprising the following components by weight part: 100KG of thermoplastic starch (TPS), 350KG of LLDPE, 70KG of MDPE, 1KG of a stabilizer, and 1-2KG of AC316. The product produced by the process has the advantages of no toxicity, high transparency, bright surface, impact resistance, tear resistance, no combustion, no moisture absorption, easy heat sealing and firmness, and is especially suitable for the requirements of various high-speed automatic packaging machineries. Thus, the product can be widely used in packaging of the cigarette industry, the printing industry, drugs, audio-visual products and various box articles, and can play a role in resisting moisture and dust.
Description
Technical field:
The present invention relates to plastic packing product technical field, be specifically related to a kind of stretch-proof agricultural film of resistance to wrinkle.
Background technology:
At film in use at present, in order to reach the different-effect of product external packaging, requirement to film is more and more higher, particularly BiOriented Polypropylene Films (BOPP), be widely used in the outer film packings such as tobacco, under long-term physical environment, can not produce fold at film surface, the film that existing film production process is produced, chemical resistant properties is poor, ink easy and heavy color is particularly bright red, green wait react with and wrinkling, separately having is exactly the not compact outward appearance that affects product in shrinking percentage small packages rear surface, high its package speed that affects of heat-sealing temperature, barrier is poor.Cause film always unsatisfactory in use.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and a kind of a kind of stretch-proof agricultural film of resistance to wrinkle take biodegradable material as base-material is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of stretch-proof agricultural film of resistance to wrinkle, is characterized in that: the component of described packing film and the weight part of each component are:
Described stablizer is general formulation, is specially toxilic acid tin octylate.
Described LLDPE density is 0.9185g/cm
3, tensile strength is that 8.3Mpa, fracture extensibility are 500%, melt flow rate (MFR) is 2g/10min.
Described MDPE density is 0.9185g/cm
3, tensile strength is that 62.78.3Mpa, fracture extensibility are 700%, melt flow rate (MFR) is 1g/10min.
Described AC316 is polyethylene wax.
The invention has the advantages that: the thermoplastic starch plastic that W-Gum, tapioca (flour) etc. are main raw material, mix with LLDPE, LDPE, HDPE etc., the product that contains this main raw material has very high environmental benefit, this environmental benefit shows with his products material thermoplastic starch powder polymer and can circulate, renewable, Sustainable development, compared with traditional petroleum polymer, thermoplastic starch greatly reduces the quantity discharged of carbon.The product of this explained hereafter is nontoxic, high transparent, surface-brightening, shock-resistant, anti tear, do not burn, nonhygroscopic, heat-sealing easily, firmly, be specially adapted to the requirement of various high speed auto packer tools.The packing that therefore can be widely used in cigarette industry, printing industry, medicine, food, makeup, daily necessities, stationery, audio-visual product and various boxlike article, plays protection against the tide, dustproof effect.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
A kind of stretch-proof agricultural film of resistance to wrinkle, is characterized in that: the component of described packing film and the weight part of each component are:
Described stablizer is general formulation, is specially toxilic acid tin octylate.
Described LLDPE density is 0.9185g/cm
3, tensile strength is that 8.3Mpa, fracture extensibility are 500%, melt flow rate (MFR) is 2g/10min.
Described MDPE density is 0.9185g/cm
3, tensile strength is that 62.78.3Mpa, fracture extensibility are 700%, melt flow rate (MFR) is 1g/10min.
Described AC316 is polyethylene wax.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
