 The rationing cloud 1S dlseoN- cred to have a pressure resistant glass lining, sealed by a nom priority plastic gASkNe Two de- Velopments in food paeGaglng give promise of breaking the 60ttleAeek and FoscUlng America from . good many of its canned food SeaFcitaeS> NEW SEALED JAR
 Most important 1S . new(y-pef- feeted substance called N0Hepol, which will serve as Q substitute foE rubber in making sealing rings for all kinds of fruit 1arS and other glass containers, There WaM he plenty of these for eVeEyohdy,
 Of equal importance, potentially, is a new type all-glaSS eeNta1neS which can be flllea and SeAled by automatic machinery Machinery, JarS and the necessary NoEepol sealing rings now are being MaMN- faetOred, and the War Production Board has granted AAA~l pElorltleS on materials to make more eQU1p- Ment This means that as soon as the output hits its stride, 1t should take care of practically all conn meEclal canning needs for the &0- nestle market, leaving the critical and eUFtalled supply of tin and steel for paekaglng food for the armed services and leNa-lease export.
 It means, according to some ANl- thoFitleS here. that an easing ef proceSsea foods restrictions is likely before the end of this year, since the shortage of tin had more to do with bringing about canned 1ooaS ratlonlng than any shortage ot Ne- tlal food,
 WAR lNTERFENED
 Patents on the vacuum glass tar and the packagiNg machine were taken out by CoNtAlner Corp. two years ago But before they could get into production, all plans were halted by the rubber shortage and the consequent inability t0 make the necessary sealing rings The development o4 NoEepol, and poS- Slbly of a couple of other SyNthetioA has removed the obstacle
 With the beginning 0e the war in the Pacific and the cutting on of rubber and tin supplies food men in every branch of tho ted~ eral government began to worty about materials for canning De- partMeNt of Agriculture and WRB ofIacialS appealed tO chemists. laboratories and the pAckAging tM~ dOStry for research on Q new SNh- stance for use in sealing food in glass, Synthetic rWbAeES already developed wouldn't work
