Auto-calculates 50% Failure Mass (Staircase Method)
20 mm solid aluminum base ensures vibration-free impact
3-jaw pneumatic release prevents dart sticking (no residual magnetism)
Versatile Solutions
From safeguarding pharmaceutical sterility to ensuring heavy-duty industrial film durability, the MLB-01 delivers standards-based impact analysis across critical sectors.

Prevent bag bursts and transport damage. The MLB-01 accurately measures the impact resistance of composite films used in frozen food, snacks, and liquid pouches, following ASTM D1709 Method A and GB/T 9639.1 for films up to 1 mm.

Critical for IV infusion bags, dialysis bags, and pharmaceutical laminated films. Supports impact testing of flexible composite films defined in YBB 00132002 using the ASTM D1709 / ISO 7765-1 free-falling dart method, helping ensure that soft medical packaging withstands handling shocks without leakage.

Solve pallet wrapping failures before they reach the warehouse floor. Using the high-energy Method B (1.50 m drop with heavier darts), the MLB-01 evaluates the puncture resistance of stretch wraps and heavy-duty shipping sacks against sharp corners, pallets, and forklifts within the film thickness range defined by the standards.

Assess the durability of greenhouse covers and mulch films against hazards like handling damage and hail impact. The Staircase Method allows R&D teams to compare resin formulations and structures for thinner yet tougher films within the applicable thickness scope of ASTM D1709 and ISO 7765-1.
Lab-Grade Precision
Eliminate human error and magnetic interference. Unlike testers that rely on electromagnets, the MLB-01 uses a precision 3-jaw pneumatic gripper to ensure clean, repeatable release for both light (50 g) and heavy (up to 2000 g) darts.

Certify Your Quality
The MLB-01 is engineered around the key free-falling dart methods used worldwide. Whether you are exporting to the US, Europe, Japan, or supplying local pharma giants, you can run impact tests using the recognized methods your customers expect.
Supports the specified dart geometries (38.1 mm / 50.8 mm) and drop heights defined by ASTM D1709 for polyethylene and other plastic films, with automated staircase evaluation.
Implements the staircase method described in ISO 7765-1 for impact resistance of plastic film and sheeting, helping ensure your test reports are accepted by European and global clients.
Designed in accordance with GB/T 9639.1-2008 for plastic films and sheets, with dimensions and procedures aligned to the equivalent ISO 7765-1 method for domestic and export orders.
Suitable for performing impact tests on flexible laminated films used in IV bags and drug sachets defined in YBB 00132002, using ASTM D1709 / ISO 7765-1 as the underlying free-falling dart method. (Not intended for rigid PVC sheets.)
Meets the mechanical setup and staircase method requirements equivalent to JIS K7124-1 for customers supplying film into Japanese or Japan-related markets.

| Feature | KHT MLB-01 (3-Jaw Pneumatic) | Competitor (Electromagnet) | Old Mechanics |
|---|---|---|---|
| Release Mechanism | ✅ 3-jaw pneumatic (instant, clean drop) | ⚠️ Electromagnet (lag / sticking risk) | ❌ Manual lift & drop |
| Light Dart Test | ✅ Smooth release (no residual attraction) | ⚠️ Often sticks due to residual magnetism | ❌ Hard to position consistently |
| Heavy Dart Test | ✅ Secure mechanical grip before release | ⚠️ May slip or fall early if magnet is weak | ❌ Uncontrolled, operator dependent |
| Base Stability | ✅ 20 mm solid aluminum plate on bench | ⚠️ Hollow chassis mounted base (more vibration) | ❌ Unstable, lightweight frames |
| Calculation | ✅ Automatic staircase calculation (M50) | ⚠️ Often manual entry into PC | ❌ Pure guesswork or rough estimates |
OEM / ODM
Tell us your film type, standards, and workflow. We will tailor fixtures, software language, and documentation to match your lab or production QC needs—then build, verify, and deliver.
We confirm your target standards (ASTM D1709 / ISO 7765-1 / GB/T 9639.1), test methods (A/B), sample types & thickness ranges, report format, and any audit or GMP-related needs before quoting.

We propose the right configuration (tower height, dart heads, weight increments, pneumatic fixtures) and provide drawings/specification sheets for your approval.

Optional UI language, logo, unit settings, and report templates. We can align the output format with your internal QC SOP or LIMS requirements.

Precision machining, pneumatic system assembly, and alignment. Every key mechanism is checked to ensure repeatable, centered impact on the sample.

Weight calibration, release stability checks, clamp consistency verification, drop-height verification, and a full functional run-through before packing.

Export-safe packaging, multilingual documentation, and remote onboarding. Factory engineers provide setup guidance and long-term spare parts support.

Why Choose KHT
A source manufacturer with independent R&D. From algorithm to base plate, every MLB-01 is built and verified in-house for repeatable impact testing.







Our dedicated R&D team implements the core staircase algorithm used to determine 50% failure mass (M50) in line with ISO 7765-1 and ASTM D1709, rather than simply assembling generic control boards.

Accuracy is non-negotiable. Every dart body and increment weight (5 g, 15 g, 30 g, 60 g, 45 g, 90 g, etc.) is calibrated on high-precision balances to stay within tight tolerances consistent with the accuracy requirements of ASTM D1709.

We replaced the problematic electromagnet concept with a 3-jaw centering pneumatic cylinder. This design eliminates residual magnetism and allows even the lightest 50 g darts to fall freely without sticking.

All control boards and pneumatic release mechanisms undergo a continuous 72-hour aging test to verify stability under high-repetition operating conditions, reducing the risk of early-life failures.

Our QC protocol includes a drop verticality check to ensure the dart hits the exact center of the sample, along with regular verification of clamp pressure and height setting accuracy.

Accuracy starts at the base. We machine a 20 mm thick solid aluminum alloy plate that sits directly on your lab bench. Unlike suspended chassis designs, this structure minimizes vibration and resonance during high-energy impacts.
Reliability
Proven performance in the global flexible packaging and medical packaging industries.
Proven Results
Discover how industry leaders use the MLB-01 to solve critical packaging failures.

A producer of frozen peas faced high bag breakage rates during cold-chain transport. Using the MLB-01 and Method A with low-temperature conditioning, they identified that their film became brittle at −20 °C. By adjusting the resin blend and verifying with impact testing, they reduced breakage by around 80%.

A saline bag supplier needed impact data aligned with YBB and ISO requirements for export to Europe. Their manual tester showed high variability. The MLB-01’s pneumatic clamping and automated staircase calculation provided consistent results, helping them pass a rigorous client audit.

A logistics hub wanted to benchmark the puncture resistance of inbound pallet wraps from different suppliers. With the MLB-01 set up for Method B (1.50 m), they created a clear ranking and selected the most cost-effective film that still met their damage thresholds.
