Definitions
- the present invention provides a method of packaging and stabilising a foodstuff comprising the steps of: forming a package comprising a peelable seal in at least a region of the package and filling the package with the foodstuff; followed by treating the package at ultra high pressure (UHP) to stabilise the foodstuff in the package without rupturing the peelable seal.
- UHP ultra high pressure
- the seal strength of the peelable seal as measured by ASTM F88-00 is in the range of from about 2N to about 3ON, preferably from 5N to about 2ON, both before and after the UHP treatment.
- This seal strength range provides mechanical robustness and leak resistance to the package, while allowing easy opening of the package by peeling.
- the sealstrength should be as low as possible consistent with maintaining product integrity.
- the sealing layer consists primarily of a polyethylene or a polypropylene. That is to say, preferably at least 50% by weight of the sealing layer is made up of a polyethylene or a polypropylene.
- suitable polyethylenes are linear low-density polyethylenes (LLDPE) and ultralow density polyethylenes (ULDPE) made by copolymerising ethylene and C3-C8 alpha-olefins. Polymers of this type are described for example in EP-A- 0351189.
- the sealing temperature of the heat sealing layer should be selected to provide the desired peel strength.
- the heat sealing temperature is defined herein as the temperature at which the sealing step is carried out.
- the polymers of the sealing layer can be selected in conventional fashion to have a heat sealing temperature in the desired range.
- the heat sealing temperature is typically from about 120 0 C to about 160 0 C, for example from about 130°C up to about 150 0 C.
- a cold-sealing film may be used, that is to say a film having a sealing temperature of less than 100 0 C, typically less than about 50 0 C, for example about ambient (20°C). The latter films are sealed simply by applying pressure at a temperature within the cold sealing temperature range. It is a surprising feature of the present invention that seal integrity can be maintained during the UHP treatment step even if the peak temperature reached during UHP treatment exceeds the sealing temperature at which the peelable seal was formed.
- the starting temperature for the UHP treatment may be ambient temperature (15-30 0 C), or the package may be preheated before application of UHP.
- the package is preheated to a temperature of at least about 70 0 C, for example at least about 80 0 C or 90 0 C before pressurisation.
