Border advanced level, it is to extrude linear low density polyethylene (LLDPE) and co-polypropylene by three or five extruder plasticizings, then is passed through
Die head is molded, and the special process such as bubble blown is processed, and product has Nantural non-toxic environmental protection, meets U.S. FDA and USDA marks
Standard, will not discharge toxic gas during heat-sealing, waste material recoverable, the high grade of transparency, high shrinkage, good heat sealability is adapted to
Device of full automatic packaging is used, and is the renewal product of traditional PVC shrink films.
2nd, as time goes on, industrialization development tradition POF polyolefin shrink films some shortcomings defect in use
Also increasingly reveal, mainly have：
1. terminal client is when using POF shrink films, to improve packaging efficiency, using the packaging facilities of more high speed, in speed
After degree is improved, traditional POF films occur that contraction is incomplete, the loose not fit phenomenon of article after packaging.
2. the phenomenons such as damaged, tear occur in packaging for some heavier large articles.
3. because the packaging facilities speed of service is too fast, it may appear that insecure, the damaged cracking phenomena of sealing.
3rd, to solve the above problems, combining tradition POF polyolefin shrink production technologies, from POE new type resins, carry out anti-
Multiple experiment, reasonable disposition solves the product defect of traditional POF films, improves properties of product.
The content of the invention：
The invention aims to overcome the product defect of traditional POF films, the performance of tradition POF film products is lifted, is carried
The method in POF polyolefin shrink films is applied for a kind of resin POE that can lift tradition POF film properties of product.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of resin POE applies the method in POF polyolefin shrink films, including raw material proportioning and technological process：

Sizing, forms the membrane tube with three-decker.15-18 DEG C of the temperature of the cooling water, can guarantee that the cooling velocity of membrane tube, cooling
The uniformity, it is ensured that the percent thermal shrinkage and physical and mechanical properties of product.
4th, biaxial tension
Membrane tube after cooling and shaping, after being heated through far-infrared ceramic baking oven, the temperature model of fusing point is being less than higher than softening point
Start vertically and horizontally to stretch after enclosing the interior stabilization through center ring.
5th, bubble blown
The membrane tube inflation after biaxial tension is molded under 80-90 DEG C of temperature conditionss, in order to effectively cool down film bubble, adopted
Three-level cooling vane is used, cooling air requires constant temperature, and constant pressure, constant just can ensure that the one of the uniform shrinkage factor of thickness of product
Vane is typically blown or upper blowing method from flat in cause property, technical requirements, air outlet gap 6-10mm, 40-60 ° of air outlet angle, air-out
It is required that low blast Wind Volume, air output >=10m3/ min, height regulation manually.Two three-level vanes typically require refrigeration, and temperature control exists
15-18 DEG C, Wind Volume sizing.
6th, thermal finalization is handled
Because POF films use high magnification biaxial stretching, thus product maintains a large amount of stress to a certain extent,
Storage transportation can produce natural shrinking and small thermal deformation, thus must carry out thermal finalization processing in process, fixed
Type temperature control is between 0-100 DEG C, and specific installation warrants storage and transportation environment temperature store in a warehouse transportation environment at 45 °,
Thermo-roll surface temperature will be controlled at 50-60 DEG C, higher than storage transport temperature.
7th, part cooling
POF products configure two-sided chilling roller or two-sided cold wind and carry out cooling treatment to film surface, protect after thermal finalization processing
Card finished product surface temperature in winding is not higher than room temperature.This processing is can be because film surface temperature be too high after winding based on film, production
Raw trickle stress release, film stretcher strain influences the processing of the later process such as cutting, bag.
8th, wind
By the POF products winding after cooling.
It is preferred that, the processing aid is the mixture of POF smooth master batch and POF anti-adhesion master batchs.
The beneficial effects of the invention are as follows：
1. low shrinkage temperature, convenient end user improves packaging speed, packing cost is reduced.
2. wider temperature shrinkage space, improves film and fits machine, allow film to be used in various new and old designs more easily
Packaging facilities.
3. appropriate convergent force and shrinkage factor, different packing materials may need different shrinkages to coordinate, must
It must be adjusted using formula, technique.
4. height heat-sealing, Hot Tack strength, for fully automatic high-speed packing machine, higher thermal glues heat seal strength, can effectively drop
Low brokenly bubble rate.
5. high mechanical stretching.Anti-tear, puncture resistant ability, it is possible to decrease brokenly bubble rate, improves the protective capability to packing material.
6. high transparency and surface gloss, allow packing material to seem more attractive.
