The Exciting World Of Lever Seal Jars

colour kilner jars

Berlin Packaging UK’s Twist Seal & Lever Seal jars offer some great domestic and commercial buyers solutions. A glass bottle maker originally made the ‘Kilner’ jar in Yorkshire called Kilner. The original Kilner bottle makers operated from 1842 until 1937. However, the Kilner patents changed hands but still have a strong presence in the packaging marketplace today.

Plastic Lever Seal Jars

The Berlin Packaging UK Lever Seal Jar Collections are made with recyclable PET plastic and come in two different designs;

  1. Lever Seal Jar
  2. Twist Seal Jar

PET – Polyethylene terephthalate – abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.

This means the jars can be put back into the circular economy – creating an eco-friendly solution for recycling plastic waste.


Lever Seal Jars In Any Colour

Lever Seal jars are extremely robust, cost-effective, and a great glass alternative.

Extra benefits include:

  • Easy to wash
  • Simple to store
  • Can hold a variety of materials and objects
  • Last a lifetime
  • Recyclable
  • Available in family sets and sizes
  • Child-friendly.

The Lever Seal jars can be colour coded to suit different styles and trends or match your brand guidelines. You can change the colour of the base to be transparent or a solid colour. You can even add your logo, labels and beautiful graphics to create the desired finish. We have shown a few examples of jars being displayed in several colour options below.


Lever Seal jars are mainly used for storing food such as rice, grains, pulps, seeds, sweets and flour. However, we have seen them being used for storing bits and bobs from around the house.

Alternative storage ideas include:

  • Nuts and bolts
  • Small candles
  • Pins and needles
  • Cotton buds
  • Crayons
  • Stationary
  • Garden accessories, including seeds
  • Boiled sweets
  • And other creative stuff.
