Key claims equipment upgrade provides better sealing

An upgraded packaging sealer provides consistent sealing temperature to eliminate ‘burn through’ and seals that do not hold, according to the manufacturer.

Key Technologies said its enhanced AVSealer includes a new ‘true temperature’ control feature as well as CE marking, and the equipment also has optional gas flush cycle to maximize production flexibility and satisfy the demands of a wide range of fresh-cut applications.

Teri Johnson, Fresh-Cut Industry Manager at Key Technology, told that the main trigger for the redesign of the AVSealer was Key’s focus on serving the world market, prompting the company to get the sealer conformity marked.

Target market

She said that the packaging sealer, as it is a semi-automatic machine, is ideal for small to medium size fresh produce packers, with larger processors more likely seeking a fully automated system.

According to Johnson, the ‘true temperature’ control component assures a consistent seal, which helps ensure package quality and the shelf life of the product.

Energy efficiency

She added that this new control also enables processors to minimise energy usage in comparison to systems employing fuzzy logic heater controls, which, she maintains, are prone to cycling between over-heating and cooling.

In addition, said Johnson, as the AVSealer has fewer moving parts than competitive heat sealing machines and features a low-maintenance venturi vacuum system, it enables trouble-free operation over several years.

The AVSealer is designed to be used with Key-supplied bags, which, the manufacturer said, come in three sizes. The company said that bags up to 18.5 inches (470 mm) wide can be sealed with the machinery at the rate of four to six bags per minute with vacuum and up to eight bags per minute without vacuum.

Chilled, frozen food sealing

And Sigpack Systems recently introduced a new sealed packaging mechanism, which it claims is supported by sensors to ensure extended sealing times for enhanced hermetic food packaging.

The manufacturer said that its new HxL horizontal flow wrapping line includes Long-Dwell sealing technology, which allows 40 times longer sealing times and higher sealing pressures than traditional processes using the 4-layer fin seal approach which due to material bulge is vulnerable to damage and prone to leakage.

Sigpack said the technology was designed to ensure packaging film thickness and product quality and is applicable to fresh, chilled and frozen food packs.

The HxL is available in two different versions – its HCL model is suitable for medium range output and can handle 150 packages per minute, while its HSL system, designed for more high speed ranges, has capacity for 350 packages per minute, added the company.
