Testing Equipment for Packaging Industry — Flexible, Blister & Corrugated Packaging QC

International Equipments is a leading manufacturer, supplier and exporter of complete laboratory testing equipment for the packaging industry in India. Built at our Mumbai facility and exported to over 60 countries, our testing instruments are installed in the QC laboratories of many of India's largest flexible packaging, blister packaging and corrugated packaging manufacturers — covering every stage of production from incoming polymer granule QC through to finished pouch, blister pack and corrugated box validation.

The packaging industry is one of the fastest-growing sectors in India, with flexible packaging in particular emerging as the highest-growth segment. FMCG, dairy, pharmaceutical, food and beverage manufacturers all depend on packaging that performs reliably — sealing in product freshness, surviving transport and storage, and presenting brand identity attractively on the retail shelf. Behind every roll of flexible laminate, every blister sheet and every corrugated carton lies a testing laboratory that has verified its mechanical properties, seal integrity, light barrier, slip behaviour and dimensional consistency before it was released for production use.

The Indian Packaging Industry — A Rapidly Growing Sector

Packaging industry has wide application & existence across the world. In India packaging industry is a rapidly growing industry with enormous potential and future growth opportunities. The Indian packaging industry has grown quickly in recent years, becoming one of the country's fastest-growing industries. In India and as well as around the globe, flexible packaging solutions have emerged as the high growth segment of the packaging industry. Flexible packaging industry has found its applicability extensively in high growth industries like FMCG, Dairy application & Pharmaceuticals.

Flexible packaging with mono layer and multilayer applications, Blister packaging, Corrugated packaging and many more innovative ways of packaging have been a boon to the Food, Oil & Pharmaceutical industries. In order to improvise the quality of packaging there are several testing standards introduced as per ASTM, ISO, Din and Bureau of Indian Standards. Few of these testing machines offered by International Equipments are Tensile Tester & Elongation Testing Machine, Dart Impact tester, Heat Sealing Machine, Coefficient of friction test, Melt Flow index Tester, Peel strength Tester, Seal strength Shrinkage testing Machine, GSM (grams square meter) test, Opacity test and so on.

Why a Complete In-House QC Lab is Essential

Packaging quality directly affects product safety, shelf life, customer experience and brand reputation. Here are the main reasons every flexible packaging, blister packaging and corrugated packaging manufacturer needs a complete in-house QC laboratory:

Food Safety & Shelf Life Depend on Seal Integrity

A snack pouch with a weak heat seal goes stale within days; a pharmaceutical blister with a poor lidding-foil seal compromises drug stability; a milk pouch with delamination leaks in transit. Heat-seal strength, peel adhesion and burst-pressure testing on every batch of laminate are the QC checks that prevent these field failures.

Machine Runnability on the Packaging Line

Flexible films must run on automatic packaging machines at high speed without dragging, jamming, or stretching. Coefficient of friction (slip), tensile strength, elongation, and gauge consistency are the tests that confirm machine runnability before the laminate reaches the customer's filling line.

Cost Control Through Master-Batch & Slip-Agent Optimisation

Slip agents, anti-block, master-batches, sealant layers — every additive costs money. QC testing identifies the minimum effective loading of each additive, eliminating costly over-dosing while still meeting customer specifications.

R&D for New Laminate Structures

Multilayer laminate development (PET-foil-PE, BOPP-MET-PE, retort pouch structures) requires extensive testing through every iteration. A complete in-house lab makes R&D fast and economical.

Recommended Testing Equipment for the Packaging Industry

1. Tensile Testing Machine

The foundation instrument for any packaging QC lab — determines tensile strength, elongation at break and modulus of films and laminates. The Single Screw Tensile Tester (lower load capacity, fixed speed) is ideal for routine flexible packaging QC; the Universal Testing Machine (twin-column, variable speed, PC software) handles higher-load corrugated and rigid packaging tests plus all the other mechanical tests.

What it tests: Tensile strength and elongation of plastic film, multilayer laminate, paper, paperboard, foil and composite packaging materials per ASTM D 882, ISO 527 and IS 13360.

2. Universal Testing Machine (UTM)

Twin-column UTM with PC software — the multi-purpose mechanical test instrument for any packaging lab handling more than one material type. Single machine handles all tensile, compression (box compression), flexural (paperboard stiffness) and peel testing on the same frame.

What it tests: Tensile, compression, flexural and peel testing of all packaging materials including corrugated box compression, rigid container top-load, multilayer laminate tensile and heat-seal strength on the same machine.

3. Heat Sealer (Laboratory)

Laboratory bench-top heat sealer with two independent temperature zones (ambient to 200°C, 0.1°C resolution) and pneumatic clamping. Produces controlled test seals at any combination of temperature and dwell time for parameter-window studies on new films and laminates. Paired with the Peel Tester for the ASTM F 88 seal-strength workflow.

What it tests: Optimisation of sealing parameters (temperature, dwell time, pressure) for plastic film, multilayer laminate and heat-seal pouch materials.

4. Digital Peel Tester

Dedicated peel and bond strength tester with 5 kg load cell and 300 mm/min ASTM-standard test speed. Direct readout of peak load. The QC workhorse for any flexible packaging or pharmaceutical packaging laboratory — economical, dedicated, easy to operate.

What it tests: Heat-seal strength of flexible packaging pouches, peel adhesion of adhesive tapes and labels, delamination strength of multilayer laminates, blister-pack lidding-foil peel.

5. COF Tester (Static & Kinetic Friction + Inclined Plane)

What it tests: Coefficient of friction (slip) of plastic film, packaging laminate, paper and paperboard — both ASTM D 1894 (horizontal plane, Static & Kinetic) and TAPPI T-815 (inclined plane, slide angle) methods.

6. Melt Flow Index Tester (MFI)

The gatekeeper between incoming polymer granules and the extruder/blow-moulder. Every batch of LDPE, LLDPE, BOPP, PP and PVC must be MFI-checked before processing. Available in Manual, Auto-cut and Fully Computerised models.

What it tests: Melt flow rate (MFR g/10 min) of polyethylene, polypropylene and PVC compounds used for film, packaging and rigid-container extrusion.

7. Dart Impact Tester

Vertical drop-dart impact tester that determines the dart weight needed to cause failure in 50% of specimens. Essential QC for shrink wrap, stretch film, pallet wrap and any film application where impact resistance to drops, knocks and rough handling matters.

What it tests: Impact strength of plastic film — particularly LDPE, LLDPE, BOPP, multilayer laminates and shrink films — by the falling-dart method per ASTM D 1709 and ISO 7765.

8. Digital Opacity Tester

Direct % opaque readout across the full 0 to 99.9% range. Built to IS 4985 and IS 12235 (Part 3) geometry. Used by light-barrier-sensitive packaging applications including dairy lamitubes (milk in tube), pharmaceutical blister packs and UV-sensitive food packaging.

What it tests: Light transmission (% opaque) of plastic films, multilayer laminates, paper and paperboard — important for light-sensitive pharmaceutical, food and dairy packaging.

9. Digital GSM Weighing Balance

Precision GSM balance for direct mass-per-unit-area measurement of cut packaging samples. Routine QC test for every roll of film, every batch of paper, every sheet of corrugated — confirms the supplier is delivering the contracted gauge.

What it tests: Grams per square metre (GSM) of paper, paperboard, plastic film, laminate and corrugated packaging materials — the fundamental gauge consistency check.

10. Hot Air Oven (Shrinkage Testing)

Precision laboratory hot air oven with PID temperature control — supports shrinkage testing per ASTM D 2732, free-shrink and constrained-shrink methods on shrink-wrap film, stretch films and heat-shrinkable labels. Also used for sample conditioning and accelerated ageing tests.

What it tests: Heat-shrinkage of shrink wrap, label sleeves, stretch film and similar heat-sensitive packaging materials at controlled temperature (typically up to 250°C).

11. Tensile Tester for Adhesives, Ceramic Tiles & Mosaics
