Seal Strength Of Laminate

Tensile strength testing and burst or creep testing.

Seal strength of laminate. Seal strength is a package attribute. Seal strength also ensures control of the peel. This is essentially the same test procedure as that described in astm f88 used to determine seal strength however the lamination bond strength testing is completed to astm f904. The seal strength also provides assurance of control of the peelable.

The heat seal strength and failure modes of laminated films with linear low density polyethylene lldpe and low density polyethylene ldpe as the sealant materials were investigated. The laminate foil is being separated from the paper at a speed of 200mm min by means of a calibrated strength testing machine the resistance of the seal is being indicated in n 15mm the results of the heat seal strength test are being indicated in a report and the resistance is being shown in a graph. Data acquired can be used to validate the package design as adequate for maintenance of integrity to monitor process performance and to confirm shelf life performance. Heat seal strength increases with platen temperature for all samples.

The heat seal strength and failure modes of laminated films with linear low density polyethylene lldpe and low density polyethylene ldpe as the sealant materials were investigated. It shouldn t be necessary to seal your laminate floor. The first thing you need to take care of is prepping the floor. Tensile seal strength testing astm f88 uses a defined width sample 25 4 mm or 1 in of the package seal perimeter.

The maximum achievable heat seal strength for laminated film using. The maximum achievable heat seal strength for laminated film using ldpe and lldpe as sealant material is 0 598 n mm and 4 02 n mm respectively. For various small and odd shaped packages the seal strength cannot be measured by standard means. Download a brochure for more information.

Although the application is quite easy it s important that you get everything right. Seal strength tester is capable of detaching a laminate through an angle of 180 degree with a jaw separation rate of 300 mm per minute with an accuracy of 2. At a frequency of 60 hz all stickpacks with a seal strength of 0 5 n cm opened within an opening delay of 2 to 6 seconds while no stickpack with a seal strength of 1 9 n cm opened within 1000. Iso 11607 addresses two types of seal strength testing.

Each misstep could lead to unwanted damage and a waste of sealant for that matter. The flooring boards come with a super hard finish that is designed to last for the life of the floor and the boards are designed to lock.
