A Look at Stripe Metallizing Technologies

There are many packaging applications where a consumer packaged goods (CPGs) company would like the brightness and some of the barrier properties offered by metallized film, but with clear segments where the customer can see the product too.  This is particularly true of fresh foods or produce, where the ability to see the actual product in the package is a necessity.  As consumers become more demanding, and CPGs have to fight for shelf space, this is a more and more common request from the marketplace. A cost effective way to produce such a package, with both metallized and clear sections, is by using a metallized web that has clear stripes in the machine direction.  This way, depending on how the pre-made pouch is made, or whether the laminated web runs on FFS equipment, the clear stripe can be oriented in the horizontal or vertical direction on the pouch. There are three basic technologies available to carry out one-pass stripe metallizing.  The first is using chill roll banding, where metal bands lay on the film as it passes over the chill drum in a drum metallizer.  The bands peel off the film after it passes through the metallizing area, leaving clear stripes behind.  These bands need to be cut to width, with significant set-up involved to properly align them.  There is […]

Stripe Metallized Barrier AlOx Pouch Award

AIMCAL Product Competition Award Winners March 2015 Packaging: Nonfood: Marketing Celplast Metallized Products, Toronto, Ontario, captured the Marketing Award at the AIMCAL winter conference.  Celplast is recognized for their role as stripe metallizer of high barrier aluminum oxide coated polyester.  Other participants in creating the package include converter Prairie State Impressions, Franklin Park, IL, and substrate supplier Camvac Ltd., Thetford, UK. The metallized zippered pouch for Gold Strike Robusto cigars from Swisher International, Inc., Jacksonville, FL combines 48-gauge PET/48-gauge aluminum oxide with stripe metallized PET/2-mil PE.  The finished package achieves multiple benefits with high barrier properties and eye-catching graphics. According to Celplast, half of the aluminum oxide-coated PET is metallized. The stripe-metallized film is then laminated to the printed web.  High barrier properties of the aluminum oxide allows Prairie State to run a single web instead of two webs reducing material costs by more than 25 percent.  The lamination also permits higher printing and pouching speeds for increased efficiency.  The resealability feature with the zipper and product visibility through stripe metallizng creates value and great shelf appeal for the consumer.  “A 25 percent cost reduction is substantial,” stated one judge. The judging panel also liked the resealability of the package.

Unique use of Stripe Metallizing in produce bag wins Celplast the AIMCAL Marketing Award

March 2014 Packaging: Food & Beverage: Marketing Celplast Metallized Products The AIMCAL Marketing Award in the Food Packaging Category went to Celplast Metallized Products, Toronto, Ontario, Canada, for metallized, light-blocking low-density polyethylene (LDPE) bags for four varieties of potato from EarthFresh Farms, another Toronto-based firm. Celplast metallizes 1.25- or 1.75-mil LDPE from Tempo Plastics Ltd., Innisfil, Ontario, and returns it to Tempo for conversion into wicketed bags. Stripe metallizing provides product visibility while blocking most of the light that would reach the potatoes in a standard poly bag. Eliminating light exposure prevents the potatoes from turning green (and bitter) and more than triples shelf life to 21 days. Bags are punched with two parallel rows of ventilation holes and printed with bilingual product and brand information as well as alternate serving suggestions. Color coding identifies Roasting (gold), Boiling (green), Baking (red) and Mashing (blue) potatoes. Judges Comments Judges noted potato bags tend to be heavier gauge film or woven. “We really haven’t seen anything like this for fresh potatoes,” said one member of the panel. “It opens the door to greater use of metallized packaging in the produce department,” predicted another.
