Checks the sealing and substrait integrity under vacuum conditions. Useful for assessing the strength of seals laminate/packaging material s substrates and preventing product contamination or evaporation.
Shoulder Weld Bond Test
Measures the strength of the welded joint between the tube body and the shoulder. Ensures that the weld won't yield and cause split during filling, sealing, or use of tubes
Seam Seal Strength Test
To assesses the strength of the longitudinal side seam. Critical for laminate/packaging material and seamed tubes to avoid seam failure during processing or use.
Filled Tube Drop Test
Simulates accidental drops to evaluate the tube’s impact resistance. Ensures product integrity during real-world handling.
Vibration Testing for Transit Scuff
Mimics transportation conditions to assess wear, label damage, or scuffing. Useful to ensure visual appeal and product safety after logistics handling. An important test to access finding product condition.
Filling and Sealing of Tubes
Verifies the efficiency and accuracy of the tube-filling and sealing process. Ensures proper sealing capabilities and helps identify damage to tube due to the filling and sealing process.
Torque Testing for Filled Tubes
Measures the torque required to open or close a cap on a filled tube. Ensures consumer ease of use and prevents accidental opening or leakage.
Torque Testing for Empty Tubes
Checks closure system integrity before filling. Ensures proper alignment and sealing torque specifications are maintained during production.
Stability Test
Evaluates how the tube and its contents hold up over time under different environmental conditions. Ensures product quality, efficiency, and compatibility with the tube and filled material.
Skewing
Assesses misalignment in sealing or tube body. Ensures aesthetic and functional quality, especially in automatic production lines where skewing can lead to rejection.
Stiffness / Tube Rigidity
Measures the tube's resistance to deformation. Important for user experience and protection of the product inside from external pressure. An important aspect for alternative filling and sealing lines.
Dip Test
Assesses the resistance of the printed tube surface to water or chemical exposure. Ensures print quality and durability under end-use conditions like bathroom use or humid environments.
Tensile Strength
Measures the maximum force the laminate/packaging material can withstand before breaking. Important for mechanical durability, handling during filling, and preventing rupture in transit.
Peel Bond Strength Test
Evaluates the bond strength between different laminate/packaging material layers or between tube layers and shoulder/closure. Ensures structural integrity under stress and over time.
Gloss Test
Quantifies the shininess or surface finish of the tube. Important for visual appeal and branding—especially in premium cosmetic packaging.
Scuff Testing
Tests resistance of printed surface against abrasion. Ensures printed graphics and labeling remain intact during handling, transit, or shelf life.
Laminate/packaging material Density Testing
Determines the density of the laminate/packaging material to understand its weight-to-area ratio. Useful in quality control, cost optimization, and material specification compliance.
Coefficient of Friction Test
Measures surface slipperiness. Critical for ensuring smooth feeding on automated production lines and controlling stacking or slippage during storage.
Tear Strength Test
Determines the resistance of the laminate/packaging material to tearing. Ensures tube doesn’t accidentally tear during use, opening, or filling. This test also refers the ease to tear open a package by the customer, thus preventing inconvenience to access the product.
Laminate/packaging material Thickness
Directly affects barrier properties, strength, and feel of the tube. Thickness consistency is crucial for functionality, appearance, and compatibility with sealing equipment.
GSM (Grams per Square Meter)
Indicates the weight of the laminate/packaging material material per unit area. Helps maintain quality consistency and supports selection of the right laminate/packaging material for various applications.
Moisture Analysis
Measures the moisture content in the laminate/packaging material . Crucial for packaging sensitive products, preventing microbial growth, and maintaining seal quality.
Top Load Test
Measures the maximum vertical compression force a carton or tube can withstand before collapsing. Ensures structural integrity during stacking in warehouses or transit.
Bursting Strength Test
Determines the pressure required to rupture the material using a hydraulic inflated rubber diaphragm. A key quality test for corrugated boxes and paperboard, reflecting durability against internal or external pressure.
Edge Crush Test (ECT)
Evaluates the crush resistance of corrugated board perpendicular to the flutes. Crucial for determining stacking strength of shipping cartons.
Ring Crush Test (RCT)
Measures the compression strength of paper or linerboard in a ring form. Used to predict the overall performance of corrugated board, especially ECT values.
Vibration Test
Simulates the real-world vibrations during transportation (road, air, rail). Helps assess the packaging's ability to protect the product inside from transit damage.
COBB Test
Determines the water absorbency of paper or board. Critical for assessing the packaging material’s resistance to moisture, ensuring dimensional stability and maintaining barrier properties.
Moisture Test/Handheld/ Digital analysis method
Measures moisture content in paper or board, using either:

Handheld devices: Quick field checks, less accurate.

Moisture analyzers (e.g., IR balance-based): Lab-grade accuracy.

Maintaining proper moisture levels ensures:

Avoiding warping

Proper bonding during carton formation

Print quality consistency

Rub Resistance Test
Measures the durability of printed or coated surfaces when rubbed against another surface.

Ensures print or label doesn’t smudge, fade, or wear off during transit, handling, or storage.

Especially important for cosmetic, pharmaceutical, and FMCG packaging, where branding and instructions must remain legible.

Opening Force Test
Evaluates the force required to open a collapsed package, such as a tube boxes, pouch boxes, blister boxes and carton.

Ensures a that the alternative box opening machines efficiency for capacity.

Crucial for tamper evidence, user convenience, and safety (e.g., in pharma, it shouldn’t open too easily or too tightly).

Stiffness Test
Measures the resistance of a material to bending or flexing at a known degree.

Affects perceived quality, machinability (during auto filling/sealing), and consumer handling experience.

Critical for mono cartons, labels, tubes, and laminate/packaging material rolls- too stiff and they crack, too soft and they collapse.

Perforation Strength
Measures the force required to tear along a perforated line in packaging.

Ensures controlled, easy opening of tear-notches, lids, or peel able seals without accidental tearing.

Important for convenience packaging, especially in food, pharma, or single-use products.

Seal Strength Test
Assesses the bond strength of sealed areas, typically via tensile testing.

Confirms seal integrity for barrier protection and product safety.

Ensures seals won’t open during transit or handling, but are also not too hard to open for the consumer.
