Packaging Trends
New items made of plastic
Applications of the still relatively new petro-chemistry remain an area of technology giving rise to many innovations in packaging. Sheeting made of polypropylene increasingly replaces cellophane. The industry is working on making compound foils more suitable for heat sealing. The mechanical processing of these can lead to problems. This is one of the reasons why Wild Werke (Germany) develops a new generation of machines in-house for its beverage brand “Capri-Sonne”. Impetus for innovation is also provided by consumer requirements. The demand for yogurt ensures that the industry improves the characteristics of the plastic beaker and the functionality of the tear-off lid. Fruit and vegetables are presented on the shelf, packed in plastic film bags. This has advantages for trading logistics. Among other advantages, foods packed directly after harvesting remain fresh for a longer period of time. An important additional benefit is that fruit and vegetables can be made into a branded product thanks to the packaging.
More speed with standards
The standardization in the size of carriers ensures the increase of efficiency in logistics. This affects e.g. pallets and the iso-container. The shrink-wrapping or winding of pallets becomes prevalent. In 1973, the trade press publishes an estimation according to which over 50 % of the companies in the GFR pack loaded pallets with plastic film. Padding film made of PE foam is introduced as transport protection for the package. And in 1972, Pelaspan-Pac comes onto the market, the S-shaped packaging chips made of expanded polystyrene.
More informations and functions
Compact (1975)

The “Krones Bloc” by machine works Kronseder (today Krones AG, D) is a fully synchronized filling system rated at 12,000 bottles per hour. It is a combination of a filler with 28 filling valves, a capper with seven capping heads and a Cronomatic labeller. Compared with conventional solutions, this system requires 50 % less space and personnel. Further advantages are its high efficiency, the reduced noise level and a minimized risk of bottle damage.
Vacuum fills (1975)

Strunck (now Bosch Packaging Technology, D) has developed a low vacuum filling machine which is especially suitable for low viscosity bulk materials. The machine type FNL B 06 applies a vacuum of up to 500 mm WG. The low pressure filling technique is suitable for filling wine and spirits, as the gasification of alcohol is low compared to other techniques.
Strapping Band (1974)

An alternative to automatic strapping machines is distributed by Hagenauer+Denk KG (D). STAHLTEX® is a polyester yarn of textile structure that is strapped around the load and secured with a self-locking metal buckle. With a hand tool the polyester band can be re-tensioned.
