Novel materials for sealant between glass jars and metal caps (09 GB 40n6 3E41)
Popis:
A multinational company based in the South-East of England is looking for novel materials for use as sealants between metal caps and glass jars, replacing the current PVC-type material. The material should be compatible for use with the present process equipment and be suitable for contact with food. The company is looking for industrial or academic partners with experience materials formulation for the developing of suitable alternative sealant.
The client is a multinational company, specialising in food packaging. The company is looking for a novel material to replace the current PVC-based sealant used between metal caps and glass jars.
Metal caps, such as those used in jam and pickle jars are sealed using a so-called Plastisol compound. This is a mixture of PVC resin and either natural or synthetic plasticisers. There is much activity within the industry to find a non-PVC replacement, which continues to be a problem as the current material has unique properties with respect to application process and in-use performance. These are summarized as:
‹i›Application‹/i›: the Plastisol is a relatively low-viscosity liquid as it is applied to the internal circumference of the cap through a nozzle. The cap is rotated during the application to enable even distribution and leveling of the compound. The lined cap is then passed through a gas oven to solidify the compound. This process is a combination of fusing of the PVC particles and absorption of the plasticiser into the PVC matrix.‹i›Performance‹/i›: at the point of application of the cap to the glass jar, the compound is heated using steam. This allows the PVC to soften and take up the profile of the glass in the sealing area, forming a high integrity pack. The closures are applied to the filled jars using either a basic pushing process or a combination of push and twist actions.
Technical Specifications / Specific technical requirements:
The client is interested in discovering or developing novel alternative materials that may be applied using current process equipment. Technologies that the company would consider include (but are not limited to) synthetic polymer chemistry, biopolymers and organic chemistry.
The compound must be liquid at room temperature (at the point of application) and fuses or cure when heated in an air oven. In addition, the material must comply with food-safety regulations. One, two or three part systems may offer useful materials but urethane-based resins are unlikely to be acceptable from the food contact perspective. Once cured, the compound would be required to form an air tight seal with the threaded jar using a similar application process to the current capping machines, which are based in the customer (filler) plants.
