material thickness in precisely defined areas of the can. Due to their incredibly thin walls, the new aerosol cans’ empty weight is comparable to that of an alu­ minium model. The double-sided PET foil lamination and wax-coated steel material is unwound, drawn out and formed. This creates a trimmed can body equipped with a valve opening and labelled on the outer side. As a specialist in aerosol cans, ­Lanico has developed a processing technique which, for the first time, pro­ vides an internal closure at the bottom of the can. For this technique, a spe­ cially shaped base is introduced in the bottom of the cylindrical can body and is closed tightly on the inside; the re­ sulting unseen inner fold has maxi­ mum pressure resistance. The can eas­ ily achieves the 18 bar classification and burst pressure above 25 bar. Thanks to the product properties described above the aerosol can Stee­ loCare is destined for shaving foams, deodorants or hairsprays. High filling pressures support the output and nebulisation of products. In the case of hairspray, the most important factor is the presence of the finest possible droplets. The seamless printed design in high quality and the smooth sur­ faces causes visually and haptically ­appealing packaging which is of par­ ticular importance in the personal care segment. Furthermore, the unique clo­ sure with a PET coated base avoids ­corrosion when stored in the humid surroundings of bathrooms. Cost-saving streamlined process route The tinplate can also facilitate the standardisation of dimensions of the component parts. This is a major ad­ vance compared to the classic 3-part aerosol cans, for which each manufac­ turer typically uses its own dimen­ sions. The production is over 10 per­ cent more cost-efficient as a result of the reduced processing steps, water, energy and coating and also scores well with its carbon footprint. The new tinplate can be easily and completely recycled after use. Thus, this meets all the require­ ments for replacing aerosol cans made of aluminium, which nevertheless have a global market volume of around eight billion units per year. The advantages of the new aerosol cans have not gone unnoticed among experts and have ­already won the German Packaging Award and the Steel Innovation Prize. tools and machinery. The innovation was developed by a technology cons­ ortium composed of the companies Lanico, Schuler Presses and Thyssen­ Krupp Rasselstein. Innovative manufacturing processes as a joint project ThyssenKrupp Rasselstein have ­optimised a high-strength steel specif­ ically for this application. This material has significantly improved elasticity that has been combined with very fine grains, which results in a very smooth surface. A special feature of the steel is the two-sided film lamination, which reduces the steps for painting and dry­ ing in the production process and cre­ ates new space for colours and labels. Compared to the production of con­ ventional aerosol cans, the expensive use of lubricants and coating for inner surfaces is eliminated. With signifi­ cantly fewer production process steps, the new can protects against corrosion that is caused by contact with the filler substance and at the integrated rim. Schuler has developed a new ma­ chine concept that uses a drawing and stretching process for producing the can’s body. This method facilitates ex­ tremely thin wall strength with reduced plate indi­ and em.
