2. HIGH METAL ADHESION IN
VACUUM METALLIZATION
FOREWORD
Welcome to the 10th edition of
the Bobst Manchester News.
Inside this issue you will find an
article about the issue of High
Metal Adhesion in vacuum
metallizing as well as an article
focusing on the Wide Web trend in
the BOPP market in India and how
BOBST is gaining market share in
the Iberian BOPP market with the
sale of a metallizer to Polivouga.
We also review drupa 2016 which
was a great success for BOBST;
we are now looking forward to the
next big exhibition, K 2016 in
October as well as our Open
House which will be held at Bobst
Manchester prior to K. We look
forward to seeing you here.

MARKET REQUIREMENTS
Metal adhesion is an issue for packaging converters worldwide due to the
poor metal to polymer substrate bonding which can occur during vacuum
metallization which results in de-lamination and ultimately leads to a
failure of the packaging. There is currently an increasing global demand
for metallized film with higher metal adhesion levels, this is due to the
market demand for increasingly complex packaging structures which
require a lamination peel strength which is appropriate for these more
complex packaging structures.
Part of the problem is the drop of surface energy on the metal side over
time which also contributes to poor lamination bonding and can lead to
problems in conversion when further laminating or printing occurs on the
coated side. Plasma treatment alone in not the answer as it is able to
increase adhesion but has no effect on the surface energy of the coating.
De-lamination leads to product rejects and loss of reputation.
IMPROVING ADHESION AND SURFACE ENERGY
Adhesion of metal to corona treated CPP is usually poor, leading to issues
with lamination. By using the BOBST AluBond™ process, the adhesion of
the metal to the CPP film can be increased, without the use of further
plasma treatment.
The surface energy of the film is also increased with the level of BOBST
AluBond™ applied. Compared to standard corona treated CPP the initial
surface energy is much higher, the higher surface energy is also retained for
longer;after 175 days the surface energy is still higher than standard
metallized CPP.

3. BOBST is gaining market share in the Iberian BOPP
market with the sale of a BOBST K5000 2450 vacuum
metallizer equipped with BOBST Hawkeye pinhole
detector and optical density monitoring system to
Polivouga based in Portugal.
POLIVOUGA ENTERS METALLIZED BOPP MARKET
The BOBST K5000 will be the first vacuum metallizer to
be installed at Polivouga’s BOPP film plant in Portugal;
the Polivouga Group owned by the Barros family has
traditionally been in the agricultural and flexible
packaging film industry, being a market leader in the
Iberian peninsula but in June 2015 decided to diversify
into BOPP film production with the purchase of a film
line and have this year added a second BOPP film line.
In order to meet their customers’ needs for metallized
BOPP film, Polivouga made the decision to purchase a
metallizer; they chose BOBST due to their strong
reputation in the market for high productivity
machines and robust process knowledge in the area of
BOPP films which requires specialist handling. Another
key advantage of the BOBST offering is the BOBST
Hawkeye for its Optical Density (OD) control and defect
reduction capabilities; the company uses Hawkeye as
a quality control mechanism and full traceability which
ensures their metallized film is of the best quality.
SPECIALIST IN BOPP METALLIZATION
BOBST have become known in the industry as
specialists in BOPP metallzation;the renowned winding
mechanism for tension control and effective heat
management has led to the BOBST K5000 becoming
the standard machine in the BOPP Film industry around
the world due to its ability to keep the film cool and to
minimise winding defects.
Polivouga began operating in 1982 with the
manufacture of film and sleeves for the agricultural
and industrial sectors.The company is based in
Albergaria-a-Velha at a high-tech facility incorporating
a state-of-the-art laboratory where quality
management is carried out.The company has a broad
customer base which includes agricultural, food and
drink, glass and ceramics companies.
POLIVOUGA INVESTS IN BOBST K5000
METALLIZER FOR IBERIAN BOPP MARKET
Commenting on the recent purchase,Tiago Barros,
General Manager from Polivouga said“Our venture
into BOPPfilm has been very successful very quickly,
to further develop our offering for our customers,we
decided to invest in a vacuum metallizer to be able to
metallize in-house.Based on BOBST’s reputation in
the market for vacuum metallizing in particular for
BOPPfilm they were our first choice,our decision was
further confirmed when we heard about the Hawkeye
system which is perfect for us as a quality control tool”
WHAT OUR CUSTOMER SAYS:

4. The BOPP film market in India has retained better
profitability in recent times and this has created a
positive environment for investment in this area. The
trend in the market is towards higher output and wider
film lines.
TREND EXTENDS TO METALLIZING MARKET
This trend is also being translated to the vacuum
metallizing market;previously 2450mm or 2850mm
vacuum metallizers have been seen as suitable but
with the move towards wider and wider film lines,
metallizers also need to be wider with 3250mm and
3650mm now being the minimum size which is required
by the market. Additionally as film line and slitter
suppliers are developing better winding characteristics
for larger diameter reels there is the opportunity to
metallize longer reel lengths and 1270mm and
1350mm diameter reels are becoming more common.
These changes in market requirements are driven by
the need to increase production output and reduce
operation cost during film metallization which are vital
in the largely commoditised film industry in India.
EXPERTS IN WIDE WEB METALLIZATION
BOBST are known as experts in the wide web market
and are the producer of the widest metallizer in the
world (K5000 4850mm) which is based in Indonesia;
BOBST’s process knowledge has enabled the design
and production of wide web metallizers that are
equipped to run large diameters at high speeds whilst
keeping the film cool through the machine’s unique
heat management system which protects the barrier
properties of the film;the BOBST renowned winding
system also produces virtually wrinkle-free film.
INVESTMENTS FROM LEADING INDIAN FILM PRODUCERS
Cosmo Films Limited, a global leader in speciality BOPP
films and Chiripal Poly Films Limited, a leading film
producer based in India have recently placed orders for
a BOBST wide web metallizer to accompany their wide
web BOPP film lines.
With eight BOPP lines & three metallizers and one
BOPP line and a metallizer on its way, Cosmo Films
enjoys a global presence with plant cum distribution
centres in US, Korea and Japan and channel partners in
more than 80 countries.The company offers range of
BOPP films for flexible packaging, lamination, labelling
and industrial applications and has several specialty
solutions for better barrier performance.
Chiripal Poly Films has established excellent quality
standards within both the domestic and global markets
since its entry into flexible packaging in 2012 and is one
of the fastest growing film producers in the sector. With
two state of the art BOPP lines, one BOPET line and a
new investment in BOPP announced for 2017, the
company goes from strength to strength.

EVENTS
drupa is the biggest event in the conversion industry and BOBSTare proud to
have been an exhibitor at every show since 1951.This year saw a record
number of attendees to the BOBSTstand resulting in sales which exceeded
expectations and beat the total from BOBST’s record-breaking drupa in 2012.
The main focus for the metallizing division was the launch of BOBST
DarkNight®,a new innovation which eliminates most film defects during the
metallization process and produces high barrier metallized films.
Naturally a key focus for the BOBSTstand was the celebration of the 125 year
anniversary;as part of the celebrations,VIPevents were held for valued
customers where high level executives could network with BOBSTtop level
management including the CEO,Jean-Pascal Bobst.
Overall,drupa 2016 was a great success for BOBSTand saw more than 50 new
enquiries for vacuum metallizing;we thank our customers for their support.
