Claims (9)

1. Fuktbeständig papperssäck, vilken uppvisar ett eller flera pappersskikt, kännetecknad av att av pappers-skikten ett eller flera har belagts med en fuktbeständig 5 membran son innehäller stärkelse, son har modifierats ge- non att i den ympa en syntetisk polymer, samt en syntetisk polymer.
2. Säck enligt patentkrav 1, kännetecknad av att ympningen har utförts genom att emulsionspolymerisera en 10 monomerblandning under närvaro av stärkelse.
3. Säck enligt patentkrav 2, kännetecknad av att som stärkelse har använts nedbruten stärkelse.
4. Säck enligt nägot av patentkraven 1 - 3, kännetecknad av att den syntetiska polymeren innehäller en 15 styren-butadien-kopolymer.
5. Säck enligt nägot av patentkraven 1-4, kännetecknad av att den syntetiska polymeren innehäller en viny1-acetat-akrylatkopolymer.
6. Säck enligt nägot av patentkraven 1-5, kän- 20 netecknad av att det beklädda papperet har en änggenom- tränglighet om ca 15 - 30 g/m2/dygn.
7. Förfarande för tillverkning av en fuktbeständig papperssäck, kännetecknad av att tili papperet fogas en fuktbeständig membran som innehäller stärkelse, som har ,;25 modifierats genom att i den ympa en syntetisk polymer, samt en syntetisk polymer, samt det pä detta sätt belagda papperet används för tillverkning av en papperssäck.
8. Förfarande enligt patentkrav 7, kännetecknad av att den fuktbeständiga membranen fogas genom att pä 30 papperet stryka en dispersion som innehäller en modifierad stärkelse och en syntetisk polymer och genom att torka papperet, varvid det första skedet för att bilda membranen lämpligast utgörs av chocktorkning.
9. Förfarande enligt patentkrav 8, kännetecknad 35 av att efter torkningen före säcktillverkningen avlägsnas den spänning vid den fuktbeständiga membranen som **: skrynklar papperet utan att söndra membranen.
