Petainer Kegs are manufactured from PET (PolyEthylene Terephthalate) with a small proportion of nylon and a brown colorant.
Fittings are made from plastic materials: POM (Polyoxymetylen), PP (Polypropylene), TPE (Thermoplastic Elastomer) and a stainless steel metal spring.
All the materials used are approved for food use by the European Union and by the FDA in the USA.
Handling
Petainer Kegs can be supplied in outer cardboard boxes or with adapters to fit existing racking systems. On conveyor lines and automated filling machines they can be lifted by the neck when empty.
Variants of the 20 and 30 litre kegs designed for use on existing filling lines are supplied in polypropylene casings.
Clip on/clip off handles are available to assist with one-person or two-person manual handling of kegs in breweries and filling plants.
Filling
Standard Petainer Kegs can be filled in small quantities using standard filling machines with an adapter from Petainer’s partner KHS. However, for commercial volumes Petainer recommends the use of specific equipment from KHS.
Variants of the 20 and 30 litre keg in polypropylene casings are available that are specifically designed for use on existing filling lines.
Hygiene and safety
Kegs, preforms and fittings are manufactured under hygienic conditions in ISO 9000 and ISO 14000 certified plants.
Disposal and recycling
PET Petainer Kegs can be easily crushed and then recycled through the municipal or commercial plastics bottle recycling infrastructure which exists in most developed markets. The fittings and cardboard carton or polypropylene casing are also recyclable.
