Packaging Testing Equipments

This is an equipment to test the Seal Integrity / Seal Strength of liquid / semi-solid filled pouches with or without gas / air, such as shampoos / oil / tea leaves in pouches / wafers / chips packed on FFS machines.

Significance:

When a master carton fails due to compressive load in stacking / warehousing, the palletized load gets transmitted to the individual pouches. This load generates extra pressure inside the filled pouches and can cause seal failure resulting in leakage of liquid / solid / gas from failed seal joint.

It is desirable to know the maximum load causing seal / seam failure in pouch.
This maximum load resulting into failure of weak seal is called Pouch Burst Strength or Pouch Compression Strength.

Principle of operation:

1. Constant rate of Loading.
2. Constant rate of Travel.

Types of tests:

1. Dynamic Compression Test (Destructive) – Press Till Failure
2. Dynamic Compression Test (Non-Destructive) – Press Till Setpoint

This equipment confirms to TAPPI / ASTM / ISO standards and is suitable to test the Bursting Strength (BS) of :

• Paper,
• Kraft Board and
• Corrugated Fiber Board

Definition :

Bursting strength of a material is defined as the maximum hydrostatic pressure required to produce rupture of the material when a controlled and constantly increasing pressure is applied through a rubber diaphragm to a circular area.

Significance :

For Paper (TAPPI T 403):

Bursting strength is widely used as a measure of resistance to rupture in many kinds of paper. The test is relatively easy and inexpensive to make and appears to simulate some end use requirements.

For Kraft Board (TAPPI T 807):

The bursting strength test of paperboard, including linerboard, is a composite measure of certain properties of the sheet structure, principally tensile strength and elongation.

In general, bursting strength is dependent on the type, proportion, preparation, and amount of fibers present in the sheet and on their formation, internal sizing, and, to some degree, the surface treatment.

While bursting strength is an empirical property, this test, in combination with grammage (basis weight), serves to define “standard grades” in commerce.

For Corrugated Fiber Board (TAPPI T 810):

The bursting strength of combined board is primarily an indication of the character of the materials used in manufacturing a fiberboard box and has value in this respect.

Bursting strength of combined board is an optional requirement of the various carrier regulations for shipping containers. The bursting strength of the component paperboard is an important control test in the paperboard mill since the conformity of the finished container is generally controlled by the bursting strength of the paperboard.

Triple-wall corrugated board cannot be tested suitably by the bursting method. Testing of double-wall board is of questionable accuracy since it is rarely possible to get sufficiently simultaneous bursts of the multiple facings.

The test is simple and rapid to execute, but it must be recognized that it is subject to serious errors if instrument, diaphragm, and gages are not properly maintained or if improper procedures are used

Capacities Available :

This is an instrument to test various forms of packages for leakage / pin hole.

Principle :

The package (pouch, blister, bottle, etc) is dipped in a suitable size container filled with water. The vacuum is applied to the container. If there is any form of leakage / pin hole in the package, air bubbles will rush out of the package.

Significance :

Pin Holes are one of the largest culprits of product rejections in Food & Pharmaceutical Products.
Pin Holes are not visible to the naked eye but often permit moisture and odor to pass through into the package and spoil the product.
It is extremely important to understand the nature and source of leakage / pin holes.

This equipment is relevant to :

1. Cosmetic Manufacturers.
2. Pharmaceutical Manufacturers.
3. Food & Beverage Manufacturers.
4. Convertors / Laminators
5. Heavy End-Users of Packaging.
6. Research Institutions.
7. Packaging Development centers.

Normally the stiffness value (Taber) of Duplex Board is taken as an indicator of the rigidity of Printed Duplex Board Cartons. However the results shown on a stiffness tester cannot be properly understood or co-related with the performance of the mini carton.

This is an equipment to evaluate maximum compressive force a carton can withstand before failing. This reading can be easily co-related with the stackability of individual printed cartons or of the larger shipper cartons.

1. Constant rate of Loading.
2. Constant rate of Travel.
