Packaging exposed to light degrades faster than you think. Our Ultraviolet Aging Test subjects materials like amber glass, cobalt glass, HDPE, and aluminum to concentrated UV radiation cycles to measure color fading, surface chalking, and structural weakening.

• Why it matters: UV-sensitive formulations (vitamin C serums, retinols, botanical extracts) demand packaging that blocks degrading light wavelengths.

• Pass criteria: No visible discoloration, no measurable tensile strength loss, and no compromise to closure integrity after the full UV exposure cycle.

• Best-performing materials: Amber Glass, Cobalt Glass, Opaque HDPE, Aluminum.

Packaging that can’t survive a temperature swing will fail your customer. The Thermal Shock Test cycles materials rapidly between extreme high and low temperatures to simulate supply chain stress — from hot shipping containers to cold retail environments.

• Why it matters: Materials like glass, PP, and HDPE must maintain structural integrity without cracking, warping, or seal failure when temperatures fluctuate.

• Pass criteria: Zero cracking, no delamination, and no leakage after repeated thermal cycling.

• Best-performing materials: PP, Glass, HDPE, EVA.

Humidity is one of the most underestimated threats to packaging performance. This test holds materials at sustained high-temperature and high-humidity conditions to assess moisture permeability, label adhesion, and formulation barrier effectiveness.

• Why it matters: Barrier protection against oxygen and moisture is critical for extending shelf life — especially for airless systems, aluminum tubes, and EVOH-layer plastics.

• Pass criteria: No dimensional distortion, no moisture ingress beyond acceptable thresholds, and stable closure torque readings.

Your packaging must survive the journey before it can sell the product. The Simulated Transportation Experiment uses vibration tables and drop-sequence protocols modeled on international freight and last-mile delivery conditions.

• Why it matters: Lightweight materials like PET, PLA, and aluminum are chosen partly for shipping efficiency — but only pass if they also absorb transit stress without failure.

• Pass criteria: No breakage, no leakage, and no cosmetic damage across simulated road, air, and courier handling cycles.

The drop test is the most direct simulation of consumer handling reality. Packaging is dropped from standardized heights onto hard surfaces at multiple orientations to assess impact resistance and post-drop seal integrity.

• Why it matters: Materials like HDPE, PP, ABS, and EVA are specifically selected for drop and impact resistance — this test confirms they deliver on that promise.

• Pass criteria: No fractures, no lid separation, and no formulation leakage after multi-angle drop sequences.

• Best-performing materials: HDPE, PP, ABS, EVA.

A closure that’s too loose leaks. A closure that’s too tight frustrates users. Torque Testing measures the precise rotational force required to open and close caps, lids, and pump assemblies — and validates that the torque value remains stable after thermal and humidity exposure.

• Why it matters: Consistent torque is critical across glass jars, aluminum tubes, and plastic bottles, especially for child-resistant and tamper-evident closures.

• Pass criteria: Opening and closing torque values fall within the specified range across the full batch, and do not degrade after environmental conditioning.

Repeated squeezing, pressing, and pumping must not degrade the packaging structure. The Compression Fatigue Test applies cyclical compressive loads to flexible and semi-rigid packaging — tubes, squeeze bottles, and airless pumps — to assess long-term structural durability.

• Why it matters: Materials like LDPE, PP, and aluminum tubes are valued for their tactile flexibility; this test ensures that flexibility doesn’t become a failure point over time.

• Pass criteria: No wall collapse, no seal failure, and no measurable thinning of material walls after the defined number of compression cycles.

The most dangerous failure in cosmetic packaging is one you can’t see. The Compatibility Test exposes each material to the actual formulation it will contain — measuring pH shifts, discoloration, swelling, leaching, and changes in formulation viscosity or efficacy over time.

• Why it matters: Materials like HDPE, PP, Glass, and PETG are chosen precisely for chemical resistance — this test confirms zero unwanted interaction between packaging and formulation.

• Test duration: Typically 3–6 months at accelerated temperature conditions to simulate shelf-life equivalency.

• Pass criteria: No measurable change in formulation pH, color, odor, or active ingredient concentration; no visible material degradation.

• Best-performing materials: Glass (100% inert), HDPE, PP, PETG.

A 0.1mm deviation at the neck of a jar can make a lid incompatible. Dimensional Specification Measurement uses precision instruments to verify that every critical dimension — diameter, wall thickness, neck finish, and height — conforms exactly to approved engineering drawings.

• Why it matters: Dimensional accuracy ensures consistent performance across automated filling lines, accurate dosing for pump systems, and proper fit for caps and closures across glass, acrylic, and plastic substrates.

• Pass criteria: All critical dimensions fall within ±tolerance specifications defined in the product brief, with Cpk values confirming process capability.

• Inspection method: Coordinate Measuring Machine (CMM) and optical comparator verification on statistically significant sample sizes per batch.
