Product Introductions
The 170ml Plastic Spice Jar is produced for commercial dry seasoning packaging where consistent neck tolerance and structural stability are required for smooth filling and secure cap engagement. With a size of 109×52mm and a calibrated 170ml capacity, the jar is designed with balanced wall thickness and reinforced base support to maintain stacking strength and dimensional consistency in bulk handling and palletized transport. Its cylindrical body also facilitates labeling and automated packing operations.
Manufacturing is carried out using food-grade plastic through multi-zone temperature-controlled injection molding. Process parameters such as melt flow, holding pressure, and cooling time are adjusted to ensure uniform cavity filling and stable thread formation. Each batch undergoes trimming, dimensional measurement, thread inspection, and surface checking before packing. Units that do not meet tolerance or appearance standards are removed to maintain repeat-order consistency and reliable cap compatibility.

Manufacturing Process
Production of the 170ml Plastic Spice Jar starts with verification of food-grade raw materials to ensure stable processing performance before molding. The jars are manufactured using injection machines with segmented temperature control, where barrel temperature, injection pressure, and cooling cycles are adjusted according to material conditions. Special attention is given to neck and thread forming, as dimensional accuracy directly affects cap matching and torque performance. Mold temperature and cooling time are controlled to minimize internal stress and prevent shrinkage deformation.
After molding, the jars undergo controlled cooling, trimming, and removal of gate residue to maintain a clean finish. Each batch is checked using thread gauges and dimensional measurement tools to confirm neck diameter, pitch, and overall height tolerance. Surface inspection is conducted to detect visual defects, and for cap-matched orders, random leak and torque tests are performed. Approved products are then packed into export cartons, with production and inspection records maintained for traceability and repeat order consistency.
Certifications
Lead Time
Production scheduling for the Plastic Spice Jar Wholesales is arranged based on confirmed order quantity, mold availability, and current production load in our injection workshop. For existing standard models, sample preparation typically requires 3–7 working days, which includes material allocation, machine setup, initial molding, and dimensional verification before dispatch. This ensures that the sample reflects actual mass production conditions, including thread accuracy and structural consistency.
For bulk orders, the standard production lead time is 15–25 days. This period covers raw material preparation, continuous injection molding, cooling stabilization, trimming, inspection, and export packing. If customized colors are required, additional time is needed for color matching, material blending, and trial molding to ensure shade consistency across the full batch. Final delivery time is confirmed prior to production start, allowing customers to align their purchasing schedule with our manufacturing and shipment planning.
Third-Party Inspection
For the Plastic Spice Jar Manufacturer, we support SGS inspection, BV inspection, and customer-appointed third-party inspection prior to shipment according to buyer requirements. Inspection can be scheduled after production is completed and goods are prepared in cartons, ensuring the evaluated samples reflect the actual shipment batch rather than pre-production pieces.
When third-party inspection is requested, we coordinate inspection timing based on production completion and warehouse arrangement. Inspectors are provided access to production records, batch quantities, carton details, and sampling support on site. Inspection scope typically includes quantity verification, dimensional measurement, thread compatibility checks, visual surface evaluation, and packaging condition assessment. Any required re-inspection or corrective handling will be completed before final container loading to ensure shipment compliance with confirmed order specifications.
FAQ
Q: Do you support OEM/ODM orders?
A: Yes, we provide full OEM/ODM support, including custom colors, logos, packaging, and cap compatibility adjustments.
Q:How is the quality controlled during production?
A: Each batch undergoes raw material verification, injection molding with controlled parameters, dimensional and thread inspection, surface inspection, and random leak tests when supplied with caps.
Q:How are the jars packed for shipment?
A: Jars are packed in PE inner bags and export-grade cartons. Custom packing options, palletization, or printed cartons are available upon request.
Q:Do you offer sample testing for cap fitting and leak?
A: Yes, random leak tests and torque tests are conducted for sample jars to ensure proper cap fit and sealing performance.
