description	The invention is a packaging method including providing a tray with heat-sealable rims; loading the tray with a product to be packaged; applying a lid on top of the tray, the tray rims and lid having contacting surfaces being made of materials which can be heat bonded to each other at a lid sealing station to effect sealing of the lid to the tray rims, the lid comprising a biaxially oriented heat-shrinkable film having a maximum shrink force, measured at the temperature in the lid sealing station during sealing, of 0.05 kg/cm in at least the transverse direction; and heat-sealing the lid to the tray rims. A modified atmosphere can be introduced between the lid and the tray. The invention is also a package including a product; a tray in which the product is placed, the tray having heat-sealable rims; and a lid heat-sealed to the tray rims, wherein the lid comprises a biaxially oriented heat-shrinkable film having a maximum shrink force of 0.05 kg/cm in at least the transverse direction.
