From Tube to Seal
This is the total number of layers in the packaging material.
What is 6 layers?
PLH stands for this.
What is Pre-Laminated Hole?
This material doesn’t belong in the LS strip, can weaken the seal, and is notorious for hanging out on the finger roller.
What is poly build up?
This must be done about 30 minutes before the splice to prevent the paper from drooping and causing open tubes.
What is setting up the splice?
This reference is used when an operator discovers an issue at sterilization, CIP, or production?
What is QMS (Quality Monitoring Scheme)?
This type of packaging requires a sterile product, sterile environment, and sterile materials.
What is aseptic packaging?
This packaging defect occurs when a seal stretches open without the packaging material breaking.
What is a blocked/cold seal?
These must be raised all the way up to ensure enough slack for a splice repair.
What are magazine rollers?
In TS Accurate Check, you cut about this distance from the sides of the pack.
What is 1mm?
These thin strips help prevent the product from flowing into the paperboard.
What are LS Strips?
This is the minimum required hydrogen peroxide concentration during spraying, and the JUMO and DMA readings must be within ±1% of each other
What is ≥ 32% hydrogen peroxide concentration?
This package integrity test uses a salt solution and an ammeter to detect ruptures in the inner PE layers by establishing electrical contact.
What is the conductivity test?
During LS/SA Teardown Pull Check, you should pull at this angle to the side of the paper.
What is 90 degrees?
This seal is formed in the jaw system by two jaws working in pairs.
What is the Transversal Seal (TS)?
When the TS is positioned under the cap, this defect is commonly observed.
What is Inverted TS/Fin Seal?
Lubricating this part is strictly prohibited because it can cause the laminate to free wheel.
What is the mandrel? (bobbin/reel holder)
LS overlap spec for Fillers 4–7 is this value (± tolerance).
What is 5.0 ± 1.0 mm?
This packaging layer provides stiffness and shape to the package.
What is the paperboard layer?
When a paper splice leaves no strip available and the package opens where the strip should bond, this critical defect is observed.
What is an open tube?
If longitudinal crease lines are not aligned properly, it is most likely due to one of these two causes affecting package formation.
What are tube twist or improper LS overlap (tube diameter)?
