摘要： A crepe process includes applying an adhesive composition to a nonwoven web, drying, and creping the nonwoven web on a creping drum. The improvement includes using an adhesive composition that includes an aqueous copolymer dispersion obtained by emulsion polymerization of a monomer mixture including 65 to 94.5% by weight of vinyl acetate, 5 to 30% by weight of ethylene, (meth)acrylamide, and 0.1 to 4% by weight of an N-methylol functional monomer. The N-methylol functional monomer constitutes from 25 to 85% by weight of the combined amounts of acrylamide and N-methylol functional monomer, which combined amounts constitute from 0.5 to 5% by weight of the monomer mixture. The emulsion polymerization is performed in the presence of 1 to 10% by weight of polyvinyl alcohol, based on the total weight of all monomers used for the polymerization. The adhesive composition does not include alkylphenol ethoxylates, phosphate ester surfactants, or sodium laureth sulfate.

摘要： A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface in a pressure nip while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.

摘要： The invention relates to a new packaging material having a starch-based barrier coating, which packaging material is characterized in that the barrier coating comprises 30 to 90 wt% of starch after a possibly present filler component has been deducted, wherein at least 20% of the starch has an average molecular weight of at least 500,000 g/mol, preferably at least 1,000,000 g/mol, and at least 20 wt% of the starch in the barrier coating is in the form of gelatinized starch particles. A fraction of 0 to 70 wt% of plasticizer in the barrier coating and a weight per unit area in the range of 3 to 80 g/m
2 , especially preferably between 12 and 40 g/m
2 , allow for the creation of a mechanically stable barrier coating, which, for example on the inside of cardboard packagings, effectively prevents the diffusion of non-polar hydrocarbons and hydrocarbon derivatives and thus protects the packaged foods against contamination. The new packaging material is simple and economical to produce at high process speeds and has the additional advantage that the new packaging material can be recycled without limitation and meets possible legal requirements related to foods.
