Coated aluminium foil for container and lid
Aluminium foil is widely regarded as the most effective barrier material in flexible packaging, giving almost perfect protection against light and suppressing any transport of matter. Foil is usually converted to flexible packaging laminates by traditional converting processes, such as lacquering or 2-component-adhesive lamination, but more and more extrusion coating and extrusion lamination are being used.
Chalco Coat's aluminium coated foil could be used for production of semi-rigid containers and its lids for food packaging. Due to its unique properties, Chalco Coat's aluminium coated foil is ideal for the reduction of cooking time, cooling and heating, thanks to an excellent thermal conductivity. Besides it provides a high barrier protection for light, gas and contamination, that improves the food conservation. With the aluminium lid, the food could be heated in air furnaces and ensure the preservation of an optimum temperature and a good state of food longer, being light weight and resistant to external agents at the same time.
Features:
1.Very good heat conductivity, that makes it suitable for freezing and re-heating.
2.Light weight that allows economizing on shortage and transport space.
3.Food can be heate by convection, fan or microwave oven.
4.Extraordinary properties for inlaying, with lacquers especially developed by our technical department for single inlay process as well as double inlay.
With above good features, our foils could be made:
Container for heat processed dairy desserts.;
Container for prepared and oven ready meal.
Container for ready to cook-frozen deserts.
Airline catering printing lids.
High-speed train catering printing lids.
