The compatibility with the environment of a packaging that is up to date
The internal flexible pocket is made up of high-quality polyolefins (LDPE, EVA, HDPE, EVOH) for the standard and barrier versions, while from material produced from renewable sources for the “Green” version.
It has no connection elements with the external corrugated cardboard casing, thus allowing easy separation and correct disposal in the paper and in the unsorted waste at the end of use.
The flexible pocket is not coloured, has no toxic additives, facilitating recycling and can be completely emptied without allowing air to come into contact with the contained product, collapsing on itself during emptying and thus preventing air from entering.
The outer box, made of over 80% recycled material, strengthens the entire structure. It guarantees protection against light, protects the valves, and it also serves as a printable surface for identification and personalization.
Minimum space required for storage
Thanks to the separate storage of the empty components, the space requirement is minimal: the internal containers are folded and stacked in the shipping carton; the boxes are supplied flat, reducing transport costs. Once filled, the cubic shape of the Politainer guarantees optimal use of the available space and ease of positioning on the pallets.
The Politainer is ideal for the packaging of chemical, pharmaceutical and food products. In the chemical industry, maximum safety and high cost-effectiveness of liquid packaging represent an indispensable standard. The polyolefins that make up the pocket allow the packaging of a wide range of products, even those classified as dangerous liquids of ADR group II and III.
Oxygen-sensitive products are protected as the barrier container, with EVOH, prevents migration through the walls and does not come into contact with air even during emptying, since the container collapses on itself.
The Politainer is produced with a technology that prevents contact with air during extrusion and is therefore free of germs or dust particles. This feature makes it suitable for use in the packaging of pharmaceutical and cosmetic products.
In the food sector, the high purity of the inner casing and the absence of odors, as well as the protection against light, make it indispensable for many liquids.
Simple filling and safe emptying
The filling of the internal casing can be done manually, semi-automatically and automatically. With normal filling, the inner pocket remains folded and automatically expands when filled. After filling, the residual air bubble is eliminated with a slight pressure of the walls and then the closure is carried out with a screw cap. After lightly pressing the nozzle downwards, the box can be closed. Now the politainer is ready, stackable and safe for transport.
The emptying of the container takes place through the same filling nozzle. Discharge of the liquid can be accomplished in different ways using the different varieties of valves available (keys, taps, pourers, adapters for the dosing pump and closures).
