Stretch wrap film

Stretch wrap or stretch film is a highly stretchable Plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat.It is frequently used to unitize pallet loads but also may be used for bundling smaller items.Types of stretch film include bundling stretch film, hand stretch film, extended core stretch film, machine stretch film and static dissipative film. stretch wrap can have several functions: • improved stability of products or packages • more efficient handling and storage of unit loads • some degree of dust and moisture protection • some degree of tamper resistance and resistance to package pilferage

Poly shrink film

Poly shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering.  Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel on a conveyor.

A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional). 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.

Shrink wrap can be used to wrap buildings. It can wrap roofs after hurricanes, earthquakes, tornadoes and other disasters. Shrink wrap can be used for environmental containments to facilitate safe removal of asbestos, lead and other hazards.

Advantages of poly shrink film are Economical Packing, Tamper evident, Prolonging Shelf Life, Neat and Presentable with Sales Appeal, Total Protection –Water Proof, Protection against Rain, Dust, Moisture, Humidity etc., it should be Usage of Shrink Machine/Shrink gun Poly.

Film embossing process

Film embossing is a mechanical process in which a flat film is transformed into an embossed product. During the process, thermal and stress fields are applied to the polymer, causing changes in the microstructure and physical dimensions of the material. The engineering analysis of the process requires the study of various aspects relating to the characterization of the microstructure before and after embossing, A variety of techniques were employed to characterize the properties and microstructure of the embossed film in relation to crystallinity, orientation, mechanical properties, and dimensions of the embossed films. The thermal treatment of the polymer film was shown to be the most significant factor in the process. By controlling the thermal treatment of the film, it is possible to manipulate the properties and dimensions of the embossed film.

 The important aspects: influencing thermal treatment include the radiation heater temperature, preheat roll temperature, line velocity, and film thickness. The initial film orientation and embossing pressure have a minor effect on the final properties of the embossed film. The main effect of the embossing pressure is on the bulk thickness of the embossed film.

 Packaging is the technology of enclosing or protecting products for distribution, storage, sale, and use. It also refers to the process of design, evaluation, and production of packages. Packaging contains, protects, preserves, transports, informs, and sells. It is a barrier from oxygeb, water vapour, dust, etc. Packages can have features that add convenience in distribution, handling, stacking, display, sale, opening, reclosing, use, dispensing, reuse, recycling, and ease of disposal.  Keeping the contents clean, fresh, sterile and safe for the intended shelf life is a primary function.

 Package development involves considerations for sustainability, environmental responsibility, and applicable environmental and recycling regulations. It may involve a life cycle assesment which considers the material and energy inputs and outputs to the package, the packaged product (contents), the packaging process, the logistics system,waste management, etc. It is necessary to know the relevant regulatory requirements for point of manufacture, sale, and use. The traditional “three R’s” of reduce, reuse, and recycle are part of waste hierarchy which may be considered in product and package development.

LD Semi Embossed & Plain Film, ises in the production of rubber sheeting , tyres , retreads , patches , and linings. These are available in different thickness, lengths and types. The film can also be used as a liner to the calendared rubber to retain the properties of rubber and also to prevent dust and other foreign matters from sticking to the rubber while calendaring and during storage. It is a high resistant film.

FLEXO PRINTING BAGS

      Flexographic printed bags (L.D.P.E, H.D.P.E) can be used for various process industries as packaging of materials. These bags are durable in quality and light in weight. Flexographic printing is used throughout the world as the process of choice for package printing. It is –for instance- used for printing on the non-porous substrates required for various types of food packaging. Typical products printed using flexography include brown corrugated boxes, flexible packaging including retail and shopping bags, food and hygiene bags and sacks, milk and beverage cartons, flexible plastics, self adhesive labels, disposable cups and containers, envelopes and wallpaper

LD Semi Embossed Film & Plastic film

              Semi-embossed film is mainly used by tyre manufacturers, tread and bonding manufacturers, conveyor belt manufacturers, rubber coated fabric manufacturers, etc. The diamond shaped embossing in the film helps in the easy removal of air between the film and rubber; while calendaring results in easy and distortion-free removal of air between the films from the rubber.

            LD Semi Embossed & Plain Film, which is available in different thickness, lengths and types and colours. Standard colours are Milky White, French Blue, Red, Yellow and Natural

                        Plastic Films are widely used in variety of applications. These Include Dairy & Water Packaging Film, Electrical Fabrication, Packaging plastic bags, HMHD/LLDP Bags etc.Crystal-clear and resistant to wrinkles, grease or water stains. Forms easily. Does not become brittle and deteriorate with age. No objectionable odor. Easily die cut, beaded, punched, embossed, laminated and sealed. Packaging: for blisters, skin packaging, transparent containers, and package windows
