Embodiment

[0064] 1000 g of potato starch was introduced into a Hobart mixer, to which 2 g of Kelzan S, 2 g of hydroxyapatite, 75 g of china clay Spes and 75 g of Hydrocarb 90 were added in sequence under low speed stirring (position 1). After all components have been added, an additional 15 minutes of mixing is performed (position 1). This mixture was introduced into the previously measured and stirred composition of 1150 g of tap water and 22 g of rapeseed oil.

[0065] After all components have been stirred (position 2) to form a liquid paste, it is introduced into the feed of the modified injection molding machine. The injection molding machine used was a Thermoware of Barneveld model EPS-10. The injection molding machine used included a mold with 10 mold cavities for forming trays each with dimensions 150*75*25mm (L*B*H) and a wall thickness of 2.5mm. Injection molding includes electric heating elements and a plunger injection device with a cutout that is thermally separated from ...

Abstract

The present application relates to methods and apparatus for coating products and coated products. Method for coating a product having a wall at least partly formed with an at least partly porous structure, preferably an at least partly open cell structure, wherein pressing on at least partly on at least one side of the wall A foil or a laminate of foils is formed, said foil or at least one layer of said laminate forming a coating of said portion of said wall.

Description

technical field [0001] The present invention relates to a method of coating a product. The invention also relates to coated products as well as devices and foils or laminates for coating products. In particular, the invention relates to such a method, device or product, wherein the coated product comprises at least one wall portion having an at least partially open pore structure. Background technique [0002] Products having a pore structure, such as an at least partially open pore structure, in at least part of the walls are known in the art. Such products are known from eg WO 96 / 30186 or WO 98 / 13184. The trade names of such products manufactured and marketed are It is a registered trademark of PaperFoam BV, Barneveld, The Netherlands. In these known methods, a suspension of at least one natural polymer (e.g. starch) in a fluid (e.g. water) is gelled and then baked in a mold at a temperature sufficient to form a network of said natural polymer , wherein a blowing age...
