Laminates, foils and tubes
The laminate foil and tubes, made by him, are mainly used for pharmaceutical products, cosmetic, chemical and food industry. There are basically two types of laminate foils: ABL (aluminium barriered laminate) и PBL (polymer barriered laminate) Both are multilayered (in most cases 5 – layered) structures of polymers and co-polymers and a barrier layer. In ABL foils, the barrier is an aluminum layer of a certain thickness (most often 12 or 20, less often 30 micron), while in PBL films the role of a barrier is played by a special polymer layer. The main manufacturer and supplier of foils for laminate tubes is Huhtamaki Germany - a world leader in the production of laminate foils and foils for flexible packaging. Laminate foils allow the application of full color quality printing on the top layer, as well as the application of additional applications such as hot / cold printing. Each laminate tube consists of a body, forehead and cap. In turn, the laminate tubes, produced from the above-mentioned foils are grouped by two main indicators: tube diameter and useful tube volume. Depending on the needs of the client, the most commonly used tubes have diameters ф25, 28, 30, 35, 40 and 50 mm. The useful volume of the tube most often varies from 25 to 250 Additional options for choice for laminate tubes are the type and color of the foreheads and caps used., as well as additional options such as a top-seal applicator.
Every user of laminate tubes should have (or be able to outsource) with the appropriate equipment for subsequent filling of the product in the tube and closing it. Depending on the type of tube used, tube filling machines and automatic machines work with hot air or on an inductive principle.
