Flexible, airtight chocolate packaging

System manufacturer Loesch Verpackungstechnik is exhibiting together with its sister company Hastamat Verpackungstechnik at ProSweets in Cologne from January 27 to 30, 2019.  Located in hall 10.1, booth G030 H039, the specialist for confectionery packaging is presenting its RCB-HS wrapping head machine used to produce hermetically sealed bars of chocolate. In addition to small chocolate items, the latest version of the LTM-DUO die-fold machine also reflects the growing popularity of tightly sealed chocolate bars.

 

Hygienic product protection and a premium look for high-quality chocolate are just as important as efficient and flexible production and packaging. Having the right equipment is therefore a top priority for any chocolate producer. These requirements are perfectly fulfilled by the packaging machinery specialists from Loesch in the latest update of the RCB-HS. “The R series for small chocolate products and bars combines a premium look and ideal product protection in an end-to-end hermetically sealed pack,” says Loesch CEO Dr. Thomas Cord. “The extremely compact RCB-HS machine platform has been rigorously designed for top performance and handles the primary packaging in modern chocolate production reliably and flexibly.” Since the prototype was presented, the innovative concept has undergone continuous development to the point of market maturity. “Since its successful launch, the platform has rapidly established itself in the market, and the concept has met with a particularly enthusiastic response in markets where climate conditions demand hermetically sealed packaging,” says Cord with pride. Consumers can enjoy products with longer shelf lives and an optimized taste and texture experience. The chocolate products are presented in the premium fold wrap look that has made LoeschPack a global market leader in this segment for decades. “With excellent performance of up to 600 packaged products per minute, the RCB-HS is unrivalled in the chocolate sector,” says Cord.

A premium look with a traditional die-fold

The RCB-HS operates continuously and produces the fold wrap in one wrapping head. It circumferentially heat-seals or cold-seals the packaging material as required. The sealing jaws always seal film against film, ensuring extremely tight packaging and preventing thermal damage to the products. For an optimum look, sealing jaws carefully affix the sealed film areas to the underside of the packaging in the discharge area. The decision fully to dispense with hot-setting glue minimizes machine soiling, reduces operating costs, and greatly simplifies operation itself. The RCB-HS uses just one hot or cold-sealable packaging material, helping to reduce costs and resources. With the help of modern film printing technology, the packaging can also be designed for a premium look and feel.

Wide range of formats and packaging options

“The RCB-HS exhibits the typical characteristics of a Loesch machine: quick and simple format changeovers within a large size range, high efficiency and performance, outstanding user-friendliness and accessibility, and top hygiene properties,” says Thomas Cord. Set-up time for a format changeover is around 60 minutes, while in most cases belt changes and cleaning can be carried out without the use of tools. The machine also features excellent availability resulting from the high quality of construction in combination with long cleaning and maintenance intervals. Optional equipment such as an autosplice device further increase OEE (overall equipment effectiveness).

In addition to the RCB-HS, the specialists from Altendorf also produce a version of the R series that can create open folds. This machine is capable of outputting up to 800 packaged products per minute. The company is working at full speed to upgrade the R series to include new format ranges, folds, performance parameters, and the ability to process alternative packaging materials such as biopolymer film.

With a larger format range and a slightly reduced output performance, the RCB-H is therefore ideal for the efficient packaging of small chocolate bars, a packaging style that is becoming increasingly popular.
