Product Description


PVC film blowing machine is suitable for PVC resin by the use of membrane technology blown film forming product specifications heat shrinkable film, and the film have the advantage of transparent film and good glossiness. The machine has a higher rate of contraction in the advantage of popular new packging materials, and it is widely used on packaging of food, beverage, tea, glass products, handicrafts, sanity wares, cosmetics, electronic products and so on.
Polyvinyl chloride, i.e. PVC heat shrinkable film is identified by high strength, transparency, waterproof, damp-proof, high antipollution and sound insulation property. As a packaging product, it could not just streamline the product packaging procedure as well as reveal the color and design and color of items. It is extensively used to packaging commodities. 


1. The unit is mainly composed of the plastic extruder, the wind central, nose installations, towing equipment, cooling equipment, heat expasion devicesm heating systems and electronic control devices.

2. Key parts, screw and barrel adopt 38CrMoAIA quality alloy steel, finished ammonification, high hardness, wear resistance, corrosion resistance and other properties.

3. Using new screw, 1; 23 diameter, and suitable for high melt viscosity, heating stable.

4. Configuration, automatic temperature control system controls the heater and cooling fan airframe so that the temperature constant throughout the process of plastination, accurate and consistent with the film production process requirements to ensure that the hot film to achieve outstanding collection of quality.

5. Model head wind central adopts special structure and it is good for plastination and cooling requirment.

6. Easy to operate: Compact structure, centralized control, a higher degree of automation.

7. Width from 400mm to 1500mm.

Heat shrinking is a procedure where a film is reheated in a constricted state such that the reduce items damaged. The family of shrink films has broadened over the years with many multilayer constructions being sold today. Shrink film attributes consist of shrink, sealability, optics, sturdiness, as well as slip.. With regard to shrink properties, there are onset.temperature, free shrink, shrink force, shrink temperature range, memory, and overall package appearance.

An equipment created to constantly wrap up to 35 packets per minute. A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional). When they are warm to orient the molecules from their preliminary arbitrary pattern, films are extended. Cooling down the film establishes the film's features till it is reheated, this creates it to shrink back towards its preliminary dimensions.

Before orientation, the molecules of a sheet or tube are randomly intertwined like a bowl of thin noodle. The molecules are coiled and twisted and have no particular alignment. However, when a draw force is imposed, the amorphous regions of the chains are straightened and aligned to the direction of orientation. By applying proper cooling, the molecules will be frozen in this state until sufficient heat energy is applied to allow the chains to shrink back. One can visualize this phenomenon by stretching a rubber band and dipping it into liquid nitrogen so as to freeze in the stretched state. The band will remain in this state as long as it is kept at sufficiently cold temperatures. However, when enough heat energy is applied, the rubber band will shrink back to its original relaxed condition.

Orientation on a industrial scale can be achieved using either of two processes:

1.Tenterframe process is used to produce a variety of "heat-set" products, with biaxially oriented polypropylene (BOPP) being the most common. Heat-setting is a process whereby a film is reheated in a constrained state such that the shrink properties are destroyed.

2.Bubble process, sometimes referred to as the tubular process. In this process, a primary tube is produced by either blowing or casting the tube onto an external or internal mandrel, respectively. It is common to use water to help cool the primary tube at this point. After the primary tube has been cooled, it is then reheated and inflated into a second bubble using air much like a balloon is blown. Upon inflation, the tube is oriented in both directions simultaneously.

Application :

PVC heat shrinkable film extruder is applicable to PVC film tubular forming technology product technologies. Blown PVC heat shrinkable film extrude features good transparency, excellent gloss, high shrinkage, etc., which is popular in today's new packaging materials as well as widely used as the outer packages of food, beverages, tea, glass products, handicrafts, sanitary wares, cosmetics, electronic products, drink containers as well as pallet tons. 

PVC heat shrinkable film is typically utilized as an overwrap on lots of kinds of product packaging, consisting of containers, boxes, drink canisters and also pallet lots. A selection of items could be confined in PVC heat shrinkable film to firm the items, unitize them, maintain them tidy or build tamper resistance. It can be the primary covering for some foods such as cheese, meats, vegetables and plants. Heat-shrink tubing is used to seal electric wiring. 

Software on service providers such as DVD or CD are typically offered in boxes that are packaged in PVC heat shrinkable film. The licenses of such software program are usually placed inside the boxes, making it difficult to view them prior to buying. This has actually questioned regarding the validity of such PVC heat shrinkable film licenses. 

PVC heat shrinkable film is often made use of publications, specifically for comics as well as adult-oriented ones and also Japanese manga, generally to stop them from reading by minors. 

PVC heat shrinkable film could be made use of covering structures. It could cover roof coverings after cyclones, quakes, hurricanes and also individual catastrophes. PVC heat shrinkable film could be made use for ecological controls to promote risk-free reduction of asbestos, lead as well as individual risks. 

PVC heat shrinkable film could be provided in a number of types. Folded up film is provided on a roll with the plastic is folded in fifty percent, item is put in the center part, the continuing to be 3 sides are sealed to make up a bag, and also the bundle after that heated up which triggers the bag to adapt as well as reduce to the item put in the bag. 

Shrink bands are used over components of bundles for tamper resistance or tags, such as a soda packaging line. It could additionally integrate 2 packages into bundles. 

PVC heat shrinkable film is used over or around the designated thing, frequently by automatic tools. It is after that heated up by a heat gun or sent through a shrink tunnel or oven for shrinking. 

PVC heat shrinkable film is additionally typically made use of within even more commercial applications utilizing a larger weight shrink film. The methods continue to be the very same with a heat shrinking procedure utilizing a hand held heat gun. The following PVC heat shrinkable film applications are coming to be a lot more extensively used and accepted. 

Various other applications

1. Industrial PVC heat shrinkable film containment of huge plant equipment or components.

2. Scaffold wrap containment of buildings or bridges.

3.Structure temporary PVC heat shrinkable film frameworks for storage space or individual company operational usages. 4. Marine PVC heat shrinkable film ping of watercrafts as well as individual vehicles.

5. PVC heat shrinkable film ping of palletized freight.

6. Catastrophe contingency backup and relief projects such as broken structures or roofing systems.

7.Heat shrinkable methods merely that, heat them up and also they shrink, or even more appropriately, they recuperate in size. A heat shrinkable sleeve begins out with a thick extruded polyolefin sheet (polyethylene or polypropylene) that is created to be cross-linkable. It makes the polyolefin do even more like a tough, heat immune, flexible product or rubber, instead compared to like a plastic product.
