Transverse heat-sealing, and severings, are effected between successive articles by heat sealing means (65). the heat sealings can be set by cold pressings.
Also the use of such a composition for heat sealing and a method of heat sealing a film using such a composition.
The inside layers have thermo-sealable properties to permit the formation of the fluid channel by heat sealing at relatively low temperatures.
The fixing can take place in the form of heat sealing, welding or by sticking.
The package is sealed by heat sealing the PET layers.
Provided is a heat-seal resin.
Film layers made from such formulated compositions have surprisingly good heat seal properties, and an especially good reduction in heat seal initiation temperature.
The outer bag (201) is closed by a second seal (207) located between the first seal (205) and the top of the bag (208).
The heat-sealing/cutting device comprises the heater unit (Hu) for heat-sealing and cutting a tubular film (F).
The beverage infusion package may be of the heat seal or non-heat seal type and is formed from cellulosic material containing at least 65 % by weight wood pulp.
Film layers made from such formulated compositions have suprisingly good heat seal properties, and an especially good reduction in heat seal initiation temperature.
A film (20) may be sealed to a tray (10) by flattening an upper edge (16) of the tray to produce a planar sealing surface (16').
All of the seams are then reinforced by means of thermosealing (according to the model), using a conventional thermosealing machine at 220°-240° in order to melt the felt.
The bag has improved toughness properties and heat-sealing characteristics.
The heat seal has a seal strength at 75°C of at least 100 grams per centimeter.
Then, heat and pressure are applied to form the heat seal.
