The present invention establishes the detection method of a set of new high temperature abrasion resistance, and cigarette is considered with the wearability of BOPP film
The position at top bottom is incorporated into from positive and negative, comprehensive, the wear-resisting control at no dead point is realized.It is thin while wearability is solved
The sliding capability of film is greatly improved simultaneously, and the limitation that former wear-resisting type film is only applicable to low speed cigarette machine is beaten
It is broken.Product newly developed is promoted the use of in tobacco factory, and client is wear-resisting to normal temperature and while high-temperature wearable approval, to upper machine width
Capacitive is also profuse in praise.
The product of above-mentioned specific embodiment 1-4 productions is taken in different tobacco factory's lab scales, pilot scale, reflection is good, especially exists
Also reflect on the packing machine of 800-1000 bags/per minute good.The product tolerance of the present invention is good, mainly：Rub on normal temperature two sides
Wipe coefficient small, it is also small and fluctuate little in high temperature.
Specific embodiment of the invention 1-4 related products have following technical indicator：
Upper epidermis coefficient of friction normal temperature is in 0.18-0.22, and high temperature (50 DEG C) is in 0.25-0.30；Layer wipes coefficient normal temperature
In 0.13-0.17, high temperature (50 DEG C) is in 0.19-0.24.
In each specific implementation of the present invention, the regulation in terms of carrying out three below to related process：
1st, the method for testing of thin film high temperature wearability is consistent with the using effect of tobacco factory or closely.New detection side
After method is set up, it is to avoid each experimental film will taking sample to tobacco factory's test-run a machine, substantially increase R＆D work efficiency and quantify height
Warm wearability index.
2nd, the selection of special additive.Slipping agent employs organic ball structure and special composition, is rubbed with extremely low
Coefficient is wiped, and high temperature friction data are also material best at present.The surface of anti-stick agent material has carried out modification, improves
The super smoothness and heat resistance of film at high temperature.High temperature sliding is better, rubs weaker, does during heat-sealing flatiron
Product out is just spotless white.
3rd, brand-new antistatic control method.The use of special top layer formula and physics neutralizing method, it is ensured that thin
The well upper machine maneuverability of film, also aids in reducing flaw caused by friction.
It is emphasized that the core technology scheme of the present invention needs to accomplish at following 4 points：
First, set up the method for testing of film wearability under the high temperature conditions.There is method of testing just to can be quantified,
Change some disturbing factors of big family expenses eye observation at present, make result more just objective, it is more convincing.
Second, find film and easily abrade the reason for turning white under the high temperature conditions and solve.Find that high temperature is smooth after research
Property influence to high-temperature wearable than larger, so must develop normal temperature and high temperature all has the film of extremely low coefficient of friction, this
Sample can just weaken the rubbing action in packaging process, and control flaw occurs.
3rd, solve scratching of the antiplastering aid to film surface.The wiping of antiplastering aid is controlled from new formula design
Hurt does harm to, and new product has carried out modification to the surface of antiplastering aid, and the heat resistance after processing is also strengthened.
4th, the antistatic property of film is controlled, also for further enhancing smoothness.
The present invention is due to having selected the main material and added material that each specific embodiment is related to, therefore the film produced
High temperature sliding capability it is splendid, institute's above machine width capacitive is especially good, be not in like product be only applicable to low speed cigarette machine lack
Fall into.
