Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania pojemników jednorazowych, w którym pojemnik wytwarza się z pulpy celulozowej w procesie termoformowania, znamienny tym, że: do pulpy celulozowej o stężeniu zawiesiny papierniczej od 0,6 do 0,8% wag. dodaje się roztwór chitozanu w wodzie o stężeniu od 1 do 2% w ilości od 1 do 15%, po czym tak uzyskaną mieszaninę poddaje się prasowaniu wstępnemu i suszeniu wstępnemu do uzyskania wilgotności od 5 do 15%; przygotowuje się mieszaninę suchej rozdrobnionej celulozy z dodatkiem sproszkowanego chitozanu w ilości od 1 do 5% wag całkowitej masy mieszaniny oraz z dodatkiem 1-metylocyklopropenu, po czym tak uzyskaną mieszaninę nanosi się na wstępnie wysuszoną pulpę celulozową na powierzchnię, która przeznaczona jest jako wewnętrzna strona pojemnika, przy czym 1-metylocyklopropen stosuje się w ilości zapewniającej obecność w pojemniku 1-metylocyklopropenu w ilości od 1 do 2 mikrograma na 1 litr pojemności wewnętrznej pojemnika; a następnie poddaje się całość prasowaniu właściwemu do uzyskania końcowego kształtu pojemnika i sprasowany pojemnik poddaje się suszeniu końcowemu. Zgłoszenie obejmuje też pojemnik jednorazowy wytworzony tym sposobem.The subject of the application is a method of producing disposable containers, in which the container is made from cellulose pulp in a thermoforming process, characterized in that: to cellulose pulp with a paper suspension concentration from 0.6 to 0.8% by weight. a solution of chitosan in water with a concentration of 1 to 2% in an amount of 1 to 15% is added, after which the mixture thus obtained is subjected to pre-compression and pre-drying to a moisture content of 5 to 15%; a mixture of dry ground cellulose is prepared with the addition of powdered chitosan in an amount of 1 to 5% by weight of the total weight of the mixture and with the addition of 1-methylcyclopropene, after which the resulting mixture is applied to the pre-dried cellulose pulp on the surface that is intended as the inside of the container wherein 1-methylcyclopropene is used in an amount that ensures that 1-methylcyclopropene is present in the container in an amount of 1 to 2 micrograms per 1 liter of container internal capacity; and then it is subjected to pressing suitable to obtain the final shape of the container and the pressed container is subjected to final drying. The application also includes a disposable container made by this method.
