Abstract
The invention discloses a kind of preparation method of multidirectional easy-to-tear film, it is related to packaging material field, the present invention rolls film substrate using roller die, intensive on described roller die to be provided with multiple sharp lug bosses, described sharp lug boss is pierced into thickness of the depth less than described film substrate of film substrate.The advantage of the invention is that, the traditional thoughtcast in this area is broken through in production technology, film substrate is repeatedly rolled using the roller die with intensive sharp protrusion portion, so that the tearing strength of film substrate in any direction significantly declines, film after processing is easily torn in multiple directions, so that user at an arbitrary position can Tear Film easily.The preparation method of multidirectional easy-to-tear film disclosed by the invention is simple, and reliability is high, and low production cost, practicality is good.
Description
Technical field
The present invention relates to packaging material field, more particularly, to a kind of preparation method of multidirectional easy-to-tear film.
Background technology
Polyester film is, using polyethylene terephthalate as raw material, sheet to be made using extrusion molding, then through two-way drawing
Stretch the thin-film material being made.It is a kind of water white transparency, glossiness film, good mechanical performance, rigidity, hardness and toughness
Height, puncture-resistant, rub resistance, high temperature resistant and low temperature, chemical proofing, oil resistivity, air-tightness and fragrance protectiveness are good, are conventional
One of barrier laminated film base material.The conventional cladding material for doing boiling packaging, printing is preferable.
Easily tearing packaging and use two ways in the market：One kind is to stamp packaging bag edge easily to tear breach.Using
This mode needs to increase special equipment and process so that cost increase production efficiency declines, and is not easily controlled it and tears
Resistance to spalling and tear direction, it is not easy to which reach user's needs tears degree.Such as our daily common disposable inner wrappings
Shampoo and condiment for instant noodles bag, are sometimes extremely hard to control tear strength, and often no scissors is cut off on hand, this
Sample allows for user experience extreme difference.Another way is to use special formulation and production technology, directly by the film of packaging bag
Base material production turns into easily tore film, but this technique is also immature at present, and cost is also very high.
The content of the invention
The present invention, can be using letter in order to solve the above-mentioned technical problem there is provided a kind of preparation method of multidirectional easy-to-tear film
The mode of single machining so that plastic sheeting is easily torn in multiple directions, so that user is at an arbitrary position
Being capable of Tear Film easily.
To achieve these goals, the present invention is adopted the following technical scheme that：A kind of preparation method of multidirectional easy-to-tear film, is adopted
Film substrate is rolled with roller die, it is intensive on described roller die to be provided with multiple sharp lug bosses, described sharp lug boss
The depth for being pierced into film substrate is less than the thickness of described film substrate
It is preferred that, the height of described sharp lug boss is less than the thickness of described film substrate.
It is preferred that, the material of described film substrate is one kind in PET, BOPP, CPP, LDPE.
It is preferred that, the number of times of described rolling is 4~5 times.
It is preferred that, the height of described sharp lug boss is the 60%~70% of the thickness of film substrate.
It is preferred that, film substrate is pressed in using rubber rollers on described roller die, roller die is rotated backward with rubber rollers.
Further, described roller die includes the first roller die, the second roller die, the 3rd roller die and the 4th roller die, corresponding,
Described rubber rollers include the first rubber rollers, the second rubber rollers, the 3rd rubber rollers and the 4th rubber rollers.
It is preferred that, described lug boss is shaped as taper.
It is an advantage of the current invention that the traditional thoughtcast in this area is broken through in production technology, using with intensive
The roller die in sharp protrusion portion repeatedly rolls film substrate so that the tearing strength of film substrate in any direction significantly declines,
Film after processing is easily torn in multiple directions, so that user at an arbitrary position can Tear Film easily.This
The preparation method of the multidirectional easy-to-tear film of disclosure of the invention is simple, and reliability is high, and low production cost, practicality is good.

Embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment one, as depicted in figs. 1 and 2, a kind of preparation method of multidirectional easy-to-tear film, PET film base material 3 is in traction
Under according to the direction of arrow pass through roller die 2, rubber rollers 1 to PET film base material 3 apply certain pressure be pressed against on roller die 2, roller die
It is intensive on 2 to be provided with multiple sharp lug bosses 4.Lug boss 4 is pierced into PET film base material 3, and sharp lug boss 4 is pierced into film
The depth of base material is less than the thickness of described film substrate 3, and after above-mentioned process, the tearing strength of PET film base material 3 is big
Amplitude declines, and user can tear this film substrate with any angle at an arbitrary position easily.Lug boss 14 is shaped as cone.
Embodiment two, as shown in figure 3, the present embodiment and the difference of embodiment one are, the present embodiment is using four groups of roller dies
With the combination of rubber rollers, PET film base material 4 sequentially passes through the first roller die 21 and the first rubber pattern 11, the second roller die 22 and second
The combination of rubber pattern 12, the 3rd roller die 23 and the 3rd rubber pattern 13 and the 4th roller die 24 and the 4th rubber pattern 14, base material is multiple
Acupuncture is extruded, it is ensured that the uniformity that base material is needled, and reduce further tearing strength, and the tear of its any direction is strong
Degree is all more uniform.
Embodiment three, the present embodiment is to combine using three groups of roller dies and rubber rollers with the difference of embodiment two.
Example IV, the present embodiment is to combine using five groups of roller dies and rubber rollers with the difference of embodiment two.
Above-described embodiment employs the PET film of 12um thickness as base material, and the height of jut 4 is 6.5-8.5um,
Certainly we can also be using the plastic sheeting of other thickness as base material, and the material of base material can be with PET, BOPP, CPP, LDPE
In any one, as long as ensure jut height for base material thickness 60%~70% i.e. can reach similar effect.Lug boss
14 shape can be cone or pyramid.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, not to present invention protection model
The limitation enclosed, for some technology contents well known to those of ordinary skill in the art, here is omitted, art technology
Personnel should be understood that on the basis of technical scheme those skilled in the art need not pay creative work i.e.
The various modifications or deformation that can be made are still within protection scope of the present invention.
