Best Quality Shrink Film

A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional).Shrink film designs will become half their size and strong plastic pieces great for adding dimension to scrapbook pages and handmade cards. Easy to cut with decorative scissors, die cut machines and punches.Films are stretched when they are warm to orient the molecules from their initial random pattern. Cooling the film sets the film's characteristics until it is reheated.this causes it to shrink back toward its initial dimensions.

Types Of  Shrink Film 

• LDPE shrink film

LDPE or Low-Density PolyEthylene shrink film is among the strongest shrink film in today’s world. Owing to its high-strength and tear-resistance, it is being widely used in a number of industries across the world. Though the film is a little hazy as compared to PVC shrink film, and it also shrinks at a little higher temperature as compared to PVC, but being environment-friendly and easily available, it is the first choice of packers.

                                        

• PVC shrink film

PVC or Poly Vinyl Chloride shrink films is one of the most popular variety of shrink film discovered in recent times. This type of shrink film is very high on clarity and gloss and has a very good shrinkability. The inherent characterstic of being printable adds to its acceptability. The film shrinks at a low temperature as compared to other shrink films.

                                                                                                 

• Polyolefin Shrink Film 

Polyolefin (POF) shrink film is a combination of PVC and LDPE shrink film as far as the characteristics go. It possesses the clarity and gloss of PVC and strength and tear-resistance of LDPE shrink film. It is food grade and can be safely applied for packing of food items.Another property of POF shrink film is that it shrinks at very low temperatures and has excellent shrinkage percentage in both the directions.                     

                                                                       

Advantages Of Shrink Bags 

• Polyolefin Shrink Bags production saves cost of 4 L sealer and hot tunnel.
• The production method is 4 times faster than manual method even faster than automatic machine. 
• The production method for Polyolefin Shrink Bags saves wastage.  
• Labour cost is saved.
• Cost of floor space is saved.
• Electricity cost is saved in the process of production of shrink bags.                                      

Shrink Films For A Variety Of Applications

• Tamper-evident bands
• Full- or partial-body roll sleeves
• Wine capsules and disk plates
• Full- or partial-body shrink sleeves
• Pressure-sensitive shrink labels
• Multi-packs

Recycling of Plastic Films

Recycling means moving plastic from the agricultural waste stream back into the manufacturing process. To make recycling a reality, one must have a system or infrastructure in place. The following are the basic components of any such system:

·         Collecting

·         Sorting

·         Reprocessing

·         Marketing

Collecting

For recycling to be effective, one must collect a lot of material, from many farms. However, used plastic film is bulky and cannot be transported very effectively.To reduce transport cost for this bulky material the farmer can use a farm type small square baler that uses tine forks for cross feeding into the baling chamber to compact the plastic on the farm.

Feed the plastic into the baler by spreading the plastic into a windrow and driving the baler into the plastic. Make windrows approximately (1 m x 0.6 m deep) 3 feet by 2 feet high. Do not hand feed plastic into baler! This could cause serious injuries if feet or hands become tangled in the plastic. Large round balers can also be used, however the resulting size and shape of bale is too hard to handle. One may also have plastic compacted at a commercial compactor.The resulting compacted volume could be reduced to 15% of the original bulky volume

Sorting

Agricultural plastic film is mainly low density polyethylene. Sorting of this material is needed because there are different plastic products and additives. For example, plastic wrap is 0.5 to 1 mil thick and has tacifiers (glue) compared to tube plastic which is 4 to 15 mil thick with no tacifiers.

Reprocessing

Agricultural plastic films must be cleaned before being converted into pellets for film or formed into moulded products like plastic lumber and fence posts. Incoming plastics must be inspected for contamination and are accepted or rejected depending on the level of contamination. Contamination includes dirt, sand, stones, grease, vegetation, water, other types of plastic, glue, tape and ultraviolet (UV) light degradation. If the film has lost its flexibility and is crinkly, it has serious ultraviolet light damage. UV damage can severely limit the recyclability of agricultural plastic film.

Plastic films are then chopped in a grinder, washed to remove contaminates, then fed into an extruder where heat and pressure melt the plastics. The molten plastic is extruded into fine strands, then cooled and chopped into pellets. These pellets are used by manufacturers to make new plastic film products.Some plastic film is chopped then melted and formed directly into moulded products.

Marketing

Recycled Film

For agriculture, plastic films could be recycled back into plastic film. This is the best since there is no need to develop a market for the recycled plastic.

Plastic Moulded Products

Here are several options for molded products such as; landscape timbers, fencing, planking for farm pens, roadside posts, benches, picnic tables and pallets.All these options require a marketing plan for selling the new products.

Poly Shrink Film Manufacturing Process

Shrink packaging has been well established for over three decades. Due to it's practical and cost related advantages, it has found its use in many industries at various stages of packaging process.

Shrink Packaging can be divided into following groups:

a)Primary- where the product is totally enclosed for protection from abrasion, dust, moisture and for improved appeal.

b)Secondary- where a group of items is wrapped together to form a Sales unit, (Six-packs of Beer, Juice etc)

c)Distribution packaging-Where product is wrapped into a distribution unit which may stacked directly on the pallet ready for transportation. When walking through supermarket one only has to look on top of the shelves to see the extent of use of this packaging method.Most grocery and high volume beverage products will use cardboard trays for added rigidity of the pack. While the use tray is not always necessary, it does provide improved handling in automated warehouses.

Shrink Packaging Process

Shrink wrapping, bundle wrapping, etc, is a process during which a product item or a group of items in wrapped in a loose sleeve or envelope of plastic film, which upon application of heat shrinks and tightly conforms to the shape of enclosed contents. The key element of this process is Shrink Film.Shrink Film can be made from a variety of materials each having different strength, shrink characteristics transparency and lustre.

Polyvinylchloride (PVC), Polypropylene (PP) and Polyethylene (PE) are the three most commonly available materials.PVC, being one of the first materials used, is now being phased out due to its toxic properties, although still used abundantly in underdeveloped countries. Low Density Polyethylene (LDPE) is best suited for general packaging applications due to its relatively high strength and low cost.

Polyethylene Shrink film is manufactured in a vertical extrusion process where ethylene granules are heated under pressure to produce Polyethylene polymer.The polymer is forced upwards through a circular extrusion die to produce a very thin walled continuous tube of material, still in a semi-molten state as it emerges from the die. A controlled supply of air is fed up through the centre of the die to stretch the tube in the radial direction, thus forming a bubble. At the same time the tube is stretched in length by winding the film at a faster than it is extruded. As the film cools, the induced stretch is "memorized" in the film. Upon reheating the film, if unrestrained, will shrink a certain percentage in the width, referred to as % Shrink in TD (transverse direction), and in the length, % shrink in MD (machine direction).At the top end of the bubble the film tube is cool enough to be flattened and wound off as Lay-flat tubing, alternatively, it can be slit at one edge to produce Centre-folded material or slit at both edges to produce Flat sheet.

Plastic Embossed Film

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a “sheet”. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.Plastic films are used in a wide variety of applications. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.Plastic films are typically formed into rolls by roll slitting. Often additional coating or printing operations are also used. Films can be modified by physical vapor deposition to make metallised films. Films can be subjected to corona treatment or can have release agents applied as needed.

Plastic films are usually thermoplastics and are formed by melting for forming the film.

• Cast – Plastics extrusion can cast film which is cooled or quenched then wound up on a roll.
• Extruded film can be stretched, thinned, or oriented in one or two directions. Blown or tubular process forces air into an extruded ring to expand the film. Flat tenter lines stretch the extruded film before annealing.
• Calender rolls can be used to form film from hot polymers
• Solution deposition is another film forming process.
• Skiving is used to scrape off a film from a solid core (sometimes used to make PTFE thread seal tape)
• Coextrusion involves extruding two or more layers of dissimilar polymers into a single film
• Lamination combines two or more films (or other materials) into a sandwich
• Extrusion coating is used to form a film onto another film or substrate
