BERICAP Technology for Beer
caps with gas barrier
and o 2xygen scavenger
for PET-bottles

BERICAP Technology
for beer and O 2 sensitive drinks in PET-bottles o 2xygen scavenging on PCO 28
Oxygen sensitive products can be protected by oxygen
scavengers. This is well known and several technologies are
available. BERICAP produces closures for carbonated and
still beverages with a built-in oxygen scavenging capacity.
The impact of an oxygen scavenging closure on the oxygen
sensitive product is shown in Chart 1. Immediately after
filling there is oxygen from various sources inside a bottle –
in the beverage, in the walls of the bottle, in the headspace
–. Modern filling technology can keep this initial
level relatively low. After filling, until consumption, oxygen
ingress occurs through the bottle and through the cap.
Ingress through the cap is possible by a poor mechanical
seal or by permeation. The oxygen scavenger integrated
in the closure will predominantly absorb the oxygen
which is or gets into the headspace after filling. The
closure contributes to preservation of the oxygen sensitive
product, but the closure can not absorb all oxygen getting
access to the beverage from other sources. BERICAP
oxygen scavenging closures –O 2S have proven in the
field to preserve O 2 sensitive products in combination
with barrier- and/or oxygen scavenging bottles.
The BERICAP SuperShorty ® O 2S and DoubleSeal O 2S
are based on BERICAP’s DoubleSeal closure concept for
carbonated soft drinks which stands for a safe mechanical
seal and high carbonation retention in cold and hot
environment. The oxygen scavenging compound
which complies with EU and
USA regulations is moulded inside the
bore seal and covers the maximum
possible surface.

time
The layer of oxygen scavenging compound is designed to
expose a maximum surface to the O 2 sensitive drink to
enhance the scavenging speed. The inner side of the top
plate and the inner surface of the boreseal are totally
covered by the oxygen scavenger. The DoubleSeal of the
closure remains totally free from any compound. To avoid
any infiltration of sterilizing liquid used for aseptic filling
the oxygen scavenging compound overlaps the lower
end of the boreseal.
BERICAP SuperShorty ® O 2S and DoubleSeal O 2S can be
applied on standard cappers. BERICAP provides technical
service to evaluate, modify and set the cappers.

Chart 2: shows the evolution of incremental total oxygen
content measured in mg/ltr. in a bottle over a period
of 6 months. The combination of a multi-layer barrier
bottle with an oxygen scavenging feature and a BERICAP
SuperShorty ® O 2S or DoubleSeal O 2S shows after 6 months
a slightly lower total oxygen content than immediately
after filling.

Chart 3: shows that the combination of a bottle with inside
barrier and the BERICAP SuperShorty ® O 2S or DoubleSeal
O 2S allows for a small incremental increase of total
oxygen content in the bottle over a period of 6 months.
This ingress of oxygen added to the initial total oxygen
content immediately after filling is too small to have a
negative impact on the content. Such negative impact is
expected only at a level of > 1 mg/ltr. total oxygen content.

Chart 4: TNO Holland have developed a test procedure
to check the speed of the oxygen scavenger performance
in a closure. The initial oxygen in the headspace unavoidable
immediately after filling is nearly fully absorbed in
about 24 hours after filling.

Chart 5: This test simulates the oxygen ingress during the
shelf life of the filled bottle. The samples having passed
the test as described in chart 4 are artificially overloaded
with oxygen. The chart shows that the oxygen scavenging
capacity of the closure is powerful enough to absorb this
artifically increased level of oxygen in about 63 hours.
Printing
We can customise SuperShorty ® O 2S and
DoubleSeal O 2S by printing up to three colours.
We can also assist with artwork origination to
ensure maximum impact whilst recognising the
constraints of printing on plastic closures.
Embossing
Embossment requires large production lots to justify
the cost of mould inserts and downtime to change
the inserts.
Colours
BERICAP has already tested and approved about
50 different pigments to give our customers an
„off the shelf” range of colours to choose from.
