This type of packaging is becoming increasingly popular as the artwork and preparation instructions can be printed straight onto the tray reducing the need for a sleeve - thus reducing cost. Skinning the tray prior to top sealing makes it possible to hermetically seal board which would usually be an unsuitable material for this. Proseal has been instrumental in the creation and development of this sealing technology.
This type of packaging is commonly used for its aesthetic appeal over anything else as it is not possible to hermetically seal this type of pack. Artwork can be printed straight onto the board and this can be used for a variety of effects. A large plus of using this material is the easily recyclable nature of the pack.
This type of tray is made from a high clarity plastic and can be sealed with a modified atmosphere - ideal for fresh produce such as berries and prepared fruit. Over recent years we have converted a large proportion of the berry market away from the traditional packaging of A-PET punnet and lid to topsealing with film. Sealing with film not only reduces cost but reduces plastic waste, making this a more eco-friendly process.
In the past decade the sandwich industry has moved away from plastic packaging. Using board means all artwork can be printed straight onto the pack this has both economic and environmental benefits. The packaging gives a 'deli feel' to the sandwich and this caters more to the modern market. We have developed a large range of bespoke machines which are able to de-nest, erect and seal the sandwich pack.
Foil trays are used for the ready to cook market and are a great convenience packaging. The customer can buy the meal, cook it and the tray is presentable enough to take straight to the table to serve. Proseal has driven development in quality and efficiency in this type of pack sealing over the years to grow with the expanding market for this tray type.
