PE foils and sheets are either smooth or embossed, made from LD-PE, HD-PE, and applied as pads in the packaging of technical products, a base material for palettes and cut-outs, sewing and reinforcement items (haberdashery, etc.). We also offer warning foils.
PET and EVA anti-slip materials – protective PET sheets are designed for protecting floors against scratches; while anti-slip EVA foils provide protection against scratches and contamination in shelves and closets
HDPE, or high-density polyethylene, is under ordinary circumstances a material of milky colour that differs from other polyethylene types by higher strength and ductility. Since the material is more consistent, the foils and packages produced from it are stronger. The HDPE bag thus has a higher load capacity than a LDPE bag of identical thickness. This is beneficial in the production of very thin bags; HDPE bag thickness is from 7 micrometers.
In addition to flexible packages, HDPE is also a very suitable material for strong packages. Best-known allocations are cosmetic bottles (detergents, shampoos), and cans.
HDPE is used also in technical applications, e.g. as septic tanks, in the production of pipes, and for sheathing of cables and harnesses. Septic tanks may have very complicated shapes and large capacities. The advantage of HDPE in these applications is its natural strength and consistency.
LDPE is a polyethylene with lower density. It is the most frequently used material in the production of foils, in particular for packaging. All simple types of disposable bags, garbage bags, and shopping bags are made just from LDPE. The reason is particularly its low price and easy processing ability.
Foils are manufactured by extrusion, either as 2D foils or hoses (tubular extrusion). Foils can be made as very thin (bags for baked goods) or thick-walled (large bags). Package thickness may be adapted to application requirements from 30 micrometers (0.030 mm) up to 200 micrometers.
Should the final package be resistant against perforation, PE foils may be laminated with another foil type improving features of the final package. For example, lamination with PET foil (polyethylene-terephthalate) is used in the production of foodstuff bags for pets. Lamination with a paperboard is applied in the production of juice packages (Tetrapack type).
The benefit of LDPE is that it can be imprinted very well. Shopping bags and large bags can be decorated with multi-colour print. This material can also be welded to achieve various shapes of pouches and bags. Recycled PE may be returned back for the production of pouches and bags, which saves the environment.
PET (polyethylene-terephthalate) is a hard and clear polymer material with extremely good mechanical features. It shows excellent tear resistance; it can resist to high pressure volumes without braking, which is used in the production of packages for beverages – PET bottles.
PET material is suitable also for the production of extruded foils. Subsequent biaxial stretching of the foil (in both directions) improves significantly the strength in both directions. It forms the required packaging material known for example from gift packs, or as a baking foil. In the foil form, PET is very resistant against water steam and gas permeability providing protection to packaged products, it also resists to effects of oils and fats included in packaged food-stuff.
PET may be combined with other materials and create multi-layer packages, the features of which are modified for the specific application – packaging of aromatic spices, cheese, smoked-meat products, etc. On customer’s request, foils may have different colours, may be imprinted, metal-coated (cosmetic industry, toothpastes), or laminated (packages for pet feedstuff).
Typical examples of PET applications include:
Fibres in textile industry – dressmaking, winter jacket wadding (padding).
Beverage bottles, in particular for sparkling and alcohol-free beverages.
High-speed boiling pouches, precooked food bags, packages for non-perishable food.
PET counts among well recyclable materials. PE bottles sorted from the municipal waste are most frequently reprocessed into fibres.
EVAC (copolymer of ethylene with vinyl acetate) is a material distinguished by strength and transparency, it is soft and flexible similar to rubber. It is manufactured with the vinyl acetate content from 2 to 40 %. With increasing share of vinyl acetate, its transparency, adhesiveness, softness, and resistance against cracks also increases. Natural non-slip characteristic is an interesting feature of this material, which is beneficial in applications such as non-slip pads for floors, cabinets, shelves, and drawers.
EVAC is resistant against mechanical stress and UV radiation. It is used in the production of various sports equipment – ski boots, bicycle seats, boxing gloves and helmets; as part of the outdoor accessories, in the production of boots (Wellingtons), etc. This materiel can also be expanded, which is used in the production of sleeping pads.
