Genpak Peterborough has been a manufacturer of high quality machinery and packaging
products for over thirty years. It was formerly known as Purity Packaging Limited, founded in 1969
by the merger of the Purity Milk Bottle Company and Canada Sealright.
Canada Sealright was engaged in manufacturing bulkan containers for the ice cream industry and
was conducting research for new methods for packaging cream and other products. It had started
a plastic thermoforming operation in 1966. After forming the 1969 merger, Purity Packaging further
developed this early research, produced a plastic creamer cup for the dairy industry and manufac-
tured the first high speed fill and seal equipment capable of producing 120 cups per minute.
During the following years high-speed coffee creamer equipment was developed with fill and seal
capacities of 300 to 2100 cups per minute. Equipment has been installed in accounts in Canada,
United States, Poland, Mexico and New Zealand. The product line became the base business for
Purity Packaging for many years.
In 1975 the first butter pat equipment capable of filling and sealing 500 cups per minute was prod-
uced for butter and spreads. Equipment has been placed in Canada, United States, Great Britain
and South Africa.
In 1976 Purity Packaging started a new plant in Columbus Ohio to produce the cups and lidstock
for the US market. These products were returned to Peterborough in 1988.
The concept for a high-speed extended shelf life coffee creamer was developed in 1982 and by
1985 the first experimental machine was produced and placed in an account for test purposes.
This machine was capable of filling and sealing 1600 regular sized creamers per minute and empl-
oyed hydrogen peroxide to sterilize the cups. This design became the foundation for a successful
Over the years Purity Packaging purchased various businesses and in 1983 these were sold to
Innopac Incorporated, a Canadian Venture capital company that went public with its first stock
issue later that same year. Purity Packaging continued as a division of the new company.
The first Extended Shelf Life production system (SC1600) was installed in a Canadian account in
1989 with the second on the following year. This system provided the dairy with the confidence to
place longer code dates on their product and gave them the marketing advantage over their comp-
etition. Subsequent machines were placed in the Canada and the United States with increased cap-
ability to 2000 cups per minute.
In 1990 The Jim Pattison Group in Vancouver, British Columbia acquired a controlling interest of
the Innopac Corporation.
Purity Packaging embarked on the aseptic creamer program in 1991. The first machine was install-
ed in a US account late in 1994 and successfully passed its FDA qualification tests in 1995. Since
that time additional installations have been successfully commissioned in a number of locations in the
US. Using this system, a significant increase in unrefrigerated shelf life can be obtained.
In 1997 The Jim Pattison Group acquired the outstanding Innopac shares and privatized the comp-
any. Purity Packaging was aligned with Genpak, part of the Foodservice Packaging Group and in
2000 Purity Packaging became the Processor Packaging Division of Genpak.
The Genpak Peterborough division maintains a Technical Services group that consists of
engineering, manufacturing and technical support personnel that design, manufacture, install and
service equipment and systems. There is also a printing and lamination department that produces
packaging products to support dairy, candy, electrical and other industries. These activities are
supported by a sales group that covers the domestic markets of Canada, and the United States
as well as international markets.
Over the past five years the company has diversified it's product range. After focusing on products
for the dairy industry, the company now provides products to the bakery, deli, candy, greenhouse
and paper industries. This diversification demonstrates Genpak Peterborough's total system
approach. The Division has the capability to develop design concepts, design and document comp-
lete systems from the concepts, build the necessary equipment, install and commission the system.
The design capabilities have been enhanced with the addition of new computer systems and the
necessary graphic support tools to complete and maintain manuals and create artwork for
A twenty-four hour service was established through an on line communication system that provides
