The Latest in Tubes

Advances in tubes and machinery.

Personal Care Tubes and More

A company has provided tubes and a bot- tle for a brand-new range of hair and skin care products. The product range compris- es shampoo, conditioner, moisturizer, face wash, body wash, and deodorant. Sam Farm- er is using 50-mm-diam 200-ml tubes and 35-mm-diam 50-ml tubes with white Softline caps along with a 50-ml roll-on deodorant bottle with printed overcap. The supplier printed the tubes and bottles in-house using a new metallic ink. It is a supplier of plas- tic components and manufactures bottles, jars, flexible tubes, and closures and offers more than 1200 standard products. The company can also custom mold items for exclusive designs. M&H Plastics; 540/504-0047;;

Tube Filler

A tube filler is designed for easy, ergonomic access. The Unipac U 2060 features a compact structure and a footprint of less than one and a half square meters. Equipped with eight stations, the system can fill semisolids such as pharmaceutical and cosmetic ointments, creams, gels, and pastes. It can handle aluminium, laminate, or polyethylene tubes, which are closed either mechanically by means of a series of folds or in a heat-sealing or hot air process. The machine can reach a maximum output of 60 tubes per minute and is intended for small- to medium-sized batches. Romaco Group, Karlsruhe, Germany; +49 (0) 721 4804 0;

Polypropylene Tube Analysis
A tube manufacturer has commissioned a life-cycle assessment of its injection molded tube with in-mold label decoration. Four differ- ent products were analyzed and compared against the company’s 100% recyclable polypropylene tube. The four tube types included a laminate tube with no post consumer recycled (PCR) plastic; a laminate tube with 32% PCR (by weight, excluding cap); an extruded tube with no PCR plastic; and an extruded tube with 32% PCR (by weight, excluding cap). Results were calculated including the tube, the cap, transportation packaging, and materials transportation. Consumer use of the tube and its disposal are not included in the impact results. In all impact categories (global warming, energy demand, acidification, eutrophication, and ecotoxicity), the report shows the firm’s tube has lower impacts than virgin industry tubes and has lower impacts than tubes with PCR in all categories except ecotoxicity. In addition to being 100% recyclable, the company’s tubes reportedly use less material than industry average tubes; they feature caps made in-house, eliminating the need to transport caps from other locations; they are made in facilities that operate on a “cleaner” electrical grid than some competitors; and the company’s injection molding process minimizes waste.
