EVOH tray is a non-toxic and odorless barrier material popular among consumers

Disposable EVOH Trays
EVOH, or ethylene vinyl alcohol copolymer, is a nontoxic and tasteless barrier material that is very popular among consumers. It is also extremely processable, which makes it the ideal material for aseptic packaging. It is also considered the most airtight compound after aluminium. The combination of these qualities makes it an ideal material for disposable EVOH trays. In addition, it has a wide range of applications. For example, it is used for sealing food containers, preserving fresh meat and pet food, and sealing salt solutions. It can also be used in microwaves to heat and seal food containers. It is also resistant to water, so it can seal liquids. It is a popular choice for airline use, as it is non-toxic and tasteless.
EVOH is used in combination with other films to form a film-coated tray. The film can be a composite film, such as polyethylene terephthalate (PET), or it can be a laminated film. The choice of film depends on the type of food that will be stored and the air-tightness needed. The film can also be printed with a pattern or text, depending on the requirements of the customer. In addition to the film, the interior of the tray can be coated with another film, such as PET or PA.
The EVOH used in the film-coated tray is used as the middle barrier layer. The outer layer is PET film, which is sucked down into the tray through a vacuum. The PET film is then laminated to the formed tray using heat radiation. This process is described in co-pending application PCT/SE2007/050190.
The rim of the tray is curved. The rim may not be exactly parallel to the bottom of the tray, but it must be at least slightly curved. This will help to maintain the shape of the tray in humid conditions. It also avoids the risk of pinholes. In addition, the rim may be punched before or after the film-coating procedure.
The present invention also addresses the problem of achieving an improved function for a disabled tray. This can be achieved by producing a film-coated tray on a compression-moulded fibre tray. The process is simple and consists of producing a film layer on the fibre material.
The process may be performed by hand or by using conventional punching equipment. The rim can be curved or straight. However, it is recommended that the portion that is to be broken be kept small. Ideally, it should be located at the upper edge of the tray. This way, the tray can be easily recycled.
The present invention also addresses the problem associated with the recycleability of disposable trays. This problem is primarily solved by producing a removable film layer on a fibre material that can be recycled. The material used is a fibre material with a density of 400-650 kg/m3. This density is low enough to resist high compressive loads, yet is strong enough for a food tray. It also has a good surface for lamination.
