Sharding of plastic film on packs is overcome

Related tags: Polyethylene terephthalate

The problem of ‘sharding’, where the plastic film covering packs of prepared fruit and salads tears apart upon opening, has been overcome by Sealed Air using its Cryovac Sealappeal product.

 Cryovac Sealappeal is claimed to offer a perfect seal and one-piece peel, every time.

The drive to reduce packaging weight for fruit and salad products, has seen amorphous polyethylene terephthalate (APET)/recycled PET trays in this market becoming thinner.

However, the reduction in weight leads to the trays distorting due to the high sealing temperatures used for standard lidding films.

The Sealappeal range now includes three structures that will seal down to 110°C, ensuring no tray distortion. A range of material thicknesses is available to suit different applications.

In addition, the ability to surface print and perforate – key attributes in the fruit and salad category – are soon to be launched.

This development will remove the need for secondary labelling of packs, further reducing packaging waste.

Posted by Geoff Davis,

I noticed over a few years and even up to most recently, that plastic milk bottles and yogurt pots (lids especially) have gotten thinner. My concern, is that all of this so-called "money-saving" will become rather fool-hardy, inasmuch that it will become potentially hazardous in the long run - I e, containers and lids bursting open, causing the contents to become wasted. This is all because of "greed" whereupon companies do not think of the consequences of their money-grabbing evil ways!
