The many variants of machineable cardboard trays are real alternatives to plastic and are kind to the environment.
Gerhard Schubert GmbH is one of the world market leaders for top-loading packaging machines (TLM). The family-owned company from Crailsheim relies on an interplay of simple mechanics, intelligent control technology and high modularity for its digital, robot-based packaging machines. The TLM packaging machines pack products of all types and sectors - from food, confectionery, beverages, pharmaceuticals and cosmetics to technical articles - in trays, cartons, boxes, bottles, tubes or tubular bags.
"Are there cardboard trays with the same functionality as plastic trays?" New answers to this question are currently being found almost daily in the development of food packaging. This is because the market is emphatically demanding the consistent elimination of unnecessary plastic. Apart from aroma tightness, cardboard is an optimal alternative in many functional matters, be it for fixing yogurt pots, for positioning stacks of cookies or for the shingled arrangement of a row of pastries. Time and again, such functions can be achieved without any significant additional expense for material and machine. A win-win for the customer, the consumer and, of course, the environment.
In the course of recent developments, three basic designs of machineable cardboard trays have emerged at Schubert, representing the most essential customer requirement: the creation of individual cavities with the aid of dividers, e.g. to keep cookies in an accurate stack.
For example, there is a version in which webs can be folded out of the side wall and the bottom without additional effort, similar to a knee joint. This version has already been in use for a few years on a Schubert machine at a major Dutch cookie manufacturer.
The second version is characterized by the all-round closed side walls. With the help of pre-glued sidewall wrappers, a flawless appearance is created that prevents crumbs from falling out. Charming side effect: due to the pre-glued design, the tray is self-supporting and does not require a single drop of glue in the packaging machine.
The third variant minimizes the free "wandering" of crumbs or crumbles between the nests. For this purpose, fully dividing partitions are folded into the tray body. The result is almost perfectly separated cavities in the bottom area as well as an attractive visual appearance.
The substitution of plastic packaging while retaining form-giving functionality will be a process of constant change. The multi-layered customer-specific requirements present development teams with new perspectives that require rethinking what already exists. The next big topic has already been brought into focus: the reliable fixation of beverage bottles in carton sleeves - without higher material consumption, of course. The market for carton packaging remains exciting.
