Product Introductions
Plastic Spice Herb Caps are developed for standardized spice and herb packaging systems, with this model built around a 48mm neck finish commonly used in mass-produced seasoning bottles. The cap adopts a 5-hole dispensing layout combined with a single-flapper internal structure, designed during mold development to balance controlled output and internal sealing performance under repeated opening and closing conditions.
The product is injection molded using selected plastic materials suitable for continuous production cycles. During manufacturing, dimensional tolerance, wall thickness, and flapper flexibility are controlled to ensure consistent fit across large batch quantities. This cap is widely applied in spice bottles, herb containers, and seasoning packaging for retail and food service projects, where stable supply, uniform specifications, and compatibility with existing bottle lines are required, making it appropriate for bulk purchasing and OEM integration.

Production Process
Production of the Plastic Spice Herb Caps is carried out through a dedicated injection molding workflow developed for high-volume output. Before production, raw plastic materials are dried and screened to maintain stable flow characteristics during molding. The mold for model C5-048M is set up with controlled cavity balance to ensure uniform wall thickness and consistent 48mm dimensional accuracy across each cycle.
During molding, processing parameters such as melt temperature, injection pressure, holding time, and cooling duration are adjusted according to material behavior and monitored throughout the run. The single-flapper structure is formed directly during molding, eliminating secondary assembly steps and reducing structural variation. After demolding, each batch undergoes trimming and handling procedures to prevent deformation before moving to the inspection stage.
Certifications
Quality Control
Quality control is applied as a continuous process rather than a final checkpoint. Incoming materials are verified against internal specifications before being released to production. During molding, in-process checks are conducted to monitor key dimensions, cap fit, and flapper flexibility to ensure proper opening and closing performance.
Post-production inspection focuses on appearance consistency, structural integrity, and functional stability of the 5-hole dispensing layout. Random sampling is performed from each production batch to verify fit on standard 48mm bottle necks and to confirm flapper response under repeated use. Only batches meeting internal tolerance and functional criteria are approved for packing and shipment.
Shipping & Transportation
Shipments of Plastic Spice Herb Caps Wholesales are arranged based on order volume, delivery schedule, and destination requirements. Small quantities and samples are usually dispatched by express courier, while medium-volume orders are handled by air freight when timing is a priority. For bulk production orders, sea freight is the standard option due to cost efficiency. Shipment methods are confirmed during order review to ensure alignment with the buyer's inventory planning and receiving capability.
Prior to dispatch, goods are packed according to the selected transport method to maintain carton integrity during handling and transit. Shipping documents, including packing lists and export declarations, are prepared based on the agreed Incoterms. We coordinate loading schedules with freight partners and monitor shipment progress until departure, ensuring that orders leave the factory in accordance with the confirmed production and delivery plan.
FAQ
Q: Can I request samples before placing a bulk order?
A: Yes. Samples are available for quality and compatibility evaluation before confirming bulk production.
Q:What is the minimum order quantity for bulk orders?
A: MOQ depends on whether the order is for the standard model or includes customization. Standard versions support lower MOQs, while customized items are evaluated based on production planning and tooling requirements.
Q:How do you ensure consistency across large batch orders?
A: Consistency is maintained through controlled injection parameters, mold cavity balance, and in-process inspections. Repeat orders are produced using the same mold and production settings whenever possible.
Q:Can the cap color or branding be customized?
A: Color customization and branding options are available for bulk orders, subject to order quantity and production feasibility.
