“I am impressed by Lako’s continuous dedication to research and design for customer-specific applications. I presented Lako with the opportunity to help my company find a mechanical solution to an industry-wide problem — air retention in gusseted bags that are packed lying down in the case. They researched and designed four specific jaw serration patterns to test in the lab with different film structures, temperatures, sealing times and pressures to identify the optimal jaw set. Although this was not implemented due to a different business priority, it was a thorough feasibility study.”

COST JUSTIFICATION | ULTRASONIC CROSS SEAL
-
Typical roll of snack food film contains 3000 linear feet.
-
3000 feet x 144 square inches per linear foot = 432,000 sq in
-
Film cost is usually 25 cents per 1000 square inches for snack food films
-
432,000 x .25/1000 = 108$ per roll
If the small chip bags have a ½” cross seal on top & bottom, we can reduce about .90” per bag with a .050” seal bead. This equates to 2700 linear feet per shift (@ .9” saved per bag running 75 BPM)
-
2700 feet / 3000 feet per roll = .9 roll per shift
-
.9 roll x $108 per roll = $97.20
-
Film savings of $97.20 per shift.
-
If they run 2 shifts/day @ 6 days/week = $1166.40 per week.
-
-
If they run 50 weeks / year = $58,320 film savings per year/per bagger
New Markets
Ability to seal through contaminants enables flexible packaging of previously canned or bottled products
Film Savings
Smaller seals, smaller packages, less expensive films
Energy Savings
No heating elements and only draws electrical power for 0.1 seconds per package
Increased Shelf-Life
Tighter seals, fewer leaks, fewer product returns
Reduced Product Scrap
Sealing through contaminants and fewer leaks
Increased Output
No warm-up time, shorter seal times and fewer leaks
