Abstract
The invention discloses a kind of 5kg, the method for packing of some electrodes, this method is encapsulated using composite membrane.Compared with the existing, composite package film of the present invention can apply to the 5kg welding rods encapsulation of automation, and product qualification rate is high.
Description
Technical field
The present invention relates to welding rod encapsulation field, more particularly to a kind of 5kg, the method for packing of some electrodes, composite membrane and
Its preparation method.
Background technology
Because every bag welding rod weighs 5 kilograms, often wrapping about some using the welding rod of specification 3.2, (single weight is about 33
Gram), therefore the common welding rod of China's production at present uses paper bag Manual Packaging.
On the one hand, paper bag Manual Packaging cost of labor is high, and labor intensity is big, and welding rod paper bag packing thing material cost is higher.
On the other hand, due to following several respects reason, the automation of paper bag packing welding rod can't be realized at present：1. welding rod into
After 5 kilograms, profile is that random 2. paper bag appearance and size can not be more than standard size after placing naturally.3. paper bag bonding can not
Completed in one or several beat Inner.
Moreover, paper bag packing can not be moistureproof, the later stage is needed to carry out damp-proof treatment.
Although present food service industry and pharmaceuticals industry in high volume take composite film packaging, food and medicine all compare
It is relatively light, and be nonmetallic, unit intensity is small, and termination does not have tip shape, rule shaping in bag is put into, by dress thing again composite membrane
It will not move.And welding rod is reviewed, it, which is often wrapped, weighs 5 kilograms, and single weight is about 33 grams, and strip, there is tip shape, sometimes also
Than sharp, profile is random after placing naturally, is enclosed after bag due to space can not be completely eliminated, therefore between welding rod
It is the certain mobile space of phase mutual, it is therefore, after existing composite membrane encapsulation and easily pierced.
Although 201310390219.2 (one kind be used for weld rod box thermal contraction packaging films) and 201310503248.5 (a kind of to answer
Close electrode packaging film and preparation method thereof) although individually disclosing a kind of packaging film of welding rod, although its heat sealability, moisture resistance
Welding rod requirement can be met, film skin-friction coefficient is moderate, but because its anti-puncture ability, therefore cannot be used for industrial life
Production, can not be used for the industrial production of automation.
The content of the invention
By being found by years of researches, if industrial flow-line automation encapsulates welding rod using composite membrane, on the one hand,
Composite membrane needs strong cementability and fastness to overcome its weight weight, on the other hand, it is necessary to have the strong anti-ability of wearing.
An object of the present invention is that a kind of 5kg of offer, the method for packing of some electrodes, this method solve biography
Paper bag Manual Packaging of uniting cost of labor is high, and labor intensity is big, the problem of non-moistureproof.
Technical scheme is：A kind of 5kg, some electrodes method for packing, this method are encapsulated using composite membrane.
The third object of the present invention is to provide a kind of welding rod composite package film.
Technical scheme is：A kind of welding rod composite package film, is made up of top layer, middle level and bottom, and the top layer is by PA groups
Into middle level is made up of LLDPE and MLLDPE, and weight ratio is 49-51：49-51, bottom is made up of LLDPE and MLLDPE, weight ratio
For 39-41：59-61.
Preferably, the skin depth is 0.011-0.013mm, intima-media thickness is 0.011-0.013mm, underlayer thickness
For 0.10-0.12mm.
The third object of the present invention is to provide a kind of preparation method of welding rod composite package film.
Technical scheme is：A kind of welding rod preparation method of composite package film, comprises the following steps:
1. the proportioning according to claim 2 prepares each layer raw material；
2. 1. step is sent into extruder after 230 DEG C of temperature fusion plastification by weight proportion through dividing with the raw material got ready
Orchestration is further separated into die head, and speed of production 55m/min shapes through being cast rod with chilling, and curtain coating rod temperature is 15-18 DEG C, automatic to survey
Thickness regulation, thin film electronic impact winding, finished product is made in packaging after cutting.
Beneficial effect：
Composite package film of the present invention is on the one hand by its unique formula, on the other hand, passes through the mutual of middle level and bottom
Effect and the thickness ratio of uniqueness so that composite package film of the invention can apply to the 5kg welding rods encapsulation of automation, product
Qualification rate is high.Packing cost is greatly reduced, integrated cost estimated only original 50%, and outward appearance improves a class, automatic anti-
Can anti-counterfeiting product after printing bar code in tide and stamp, packaging bag.
Explanation of nouns
In PA- polyamide, the present invention, PA uses the PA6 of German BASF.
In LLDPE- LLDPEs, the present invention, LLDPE- is preferred to use the U.S. and contained auspiciousness (Si Tailong) difficult to understand
LLDPE。
In MLLDPE- metallocene linear low density polyethylenes, the present invention, MLLDPE is preferred to use Exxon Chemical
MLLDPE。
