Import Film Shrinkage Tester Thermal Shrink Tester — Buy in Bulk from Supplier in China

The GBK‑D1 Film Shrinkage Tester from Guangzhou GBPI Packaging Equipment Co., Ltd. is designed to evaluate the linear thermal shrinkage of heat‑shrinkable films. It measures shrinking force, contraction force and shrinkage ratio according to ASTM D2732, ISO 14616 and DIN 53369. The unit incorporates a tension sensor, a displacement sensor and an air‑heating chamber that brings the sample to the target temperature before cooling at 23 °C. Test data are recorded automatically for later analysis.

The tester can handle films based on polyethylene, ethylene copolymers and their mixtures, which represent the majority of commercial heat‑shrink films. Typical industry practice requires a shrinkage stress tolerance of ±5 % and a measurement repeatability of 0.1 N, which the GBK‑D1 meets through calibrated sensors. While the supplier does not publish a specific certification, the equipment conforms to the listed international standards, a common requirement for laboratories and quality‑control departments. Compared with generic shrink testers, the GBK‑D1 offers a built‑in cooling stage that matches the standard ambient temperature of 23 °C used in most specifications.

Users such as plastic film manufacturers, petrochemical processors and independent testing agencies use this tester to optimise film formulation and production parameters. The machine is typically ordered in a single unit, with delivery terms negotiated directly with the supplier; no minimum order quantity is stated in the listing. Buyers should confirm Incoterms, payment schedule and warranty coverage before finalising the contract.
