Product Introductions
Single-Flapper Plastic Cap is developed as a standard dispensing closure for plastic spice jars, with the structure defined at the tooling stage to ensure stable output in batch production. The cap adopts a 10-hole single-flapper configuration, where the flapper thickness, hinge position, and opening angle are set to maintain consistent dispensing performance after repeated opening and closing cycles.
During manufacturing, the cap body and flapper are produced under controlled injection molding parameters to reduce dimensional deviation between cavities. Assembly tolerance is managed to ensure proper flapper sealing without excessive friction, which helps limit moisture ingress during normal storage and handling.
The overall geometry and material selection are optimized for automated assembly and repeat orders, allowing the C1-048M to be supplied as a stable SKU or integrated into OEM projects that require long-term specification consistency.

Production Process
The production of the Single-Flapper Plastic Cap follows a standardized manufacturing sequence designed for dimensional consistency and stable batch output.
Plastic raw materials are first inspected for material grade and melt flow stability before entering injection molding. The cap body and flapper components are molded using dedicated tooling, with process parameters controlled to minimize cavity-to-cavity variation. Mold temperature, injection pressure, and cooling time are set according to material behavior to maintain consistent wall thickness and structural integrity.
After molding, components are allowed to stabilize before assembly. The flapper is installed under defined tolerance limits to ensure proper opening resistance and sealing alignment. Functional checks are conducted during assembly to confirm smooth flapper movement without sticking or excessive looseness.
Finished caps are subjected to random sampling for dimensional verification and basic functional testing before packing. This production flow is applied consistently across repeat orders to maintain specification stability for long-term supply programs.
Certifications
Sample Policy
Samples of the Plastic Cap Manufacturer are available for evaluation before bulk ordering. Samples are mainly provided to allow buyers to verify jar compatibility, dispensing performance, and material feel under actual usage conditions.
Standard samples are taken from existing production batches to reflect the same structure and material used in mass production. For projects involving customization, samples are arranged after technical feasibility is reviewed and sample requirements are confirmed.
Sample lead time depends on availability and customization scope. Shipping method and cost are discussed in advance, and samples are typically sent by air for faster delivery. Sample charges and freight terms are clarified before dispatch.
Sample approval serves as a reference for bulk production. Final specifications, packaging, and order quantity are confirmed based on the approved sample to ensure consistency between sample and mass production.
Packaging & Shipping
Packaging for the Plastic Cap Wholesales is arranged according to order quantity, transport method, and handling requirements. Finished caps are packed after final inspection, with packing density controlled to prevent deformation during stacking and transit.
Standard packaging uses inner poly bags to separate components, followed by outer export cartons. Carton size and loading quantity are calculated to balance protection and space efficiency for bulk shipments. For mixed-product orders, caps are packed and labeled by model to support warehouse identification and destination sorting.
Shipping methods are selected based on shipment volume and delivery schedule. Sea freight is typically used for bulk orders, while air freight may be arranged for samples or urgent replenishment. Export packing, carton marking, and documentation are prepared in accordance with standard international shipping procedures to ensure smooth customs clearance and container loading.
Packaging configuration and shipping arrangements are confirmed with the buyer prior to dispatch to ensure alignment with logistics planning and receiving requirements.
FAQ
Q: What jars is the Single-Flapper Plastic Cap compatible with?
A: This cap is designed for plastic spice jars with matching neck specifications. Compatibility is confirmed based on jar neck diameter, thread structure, and tolerance range before order confirmation.
Q:What is the minimum order quantity?
A: MOQ depends on whether the order is standard or includes customization. Standard orders generally have a lower MOQ, while customized projects are evaluated separately.
Q:What payment methods do you accept?
A: We accept T/T (bank transfer), L/C (letter of credit), PayPal, and other internationally recognized payment methods. For first-time orders, a partial prepayment is usually required, with the balance settled before shipment.
Q:Is logo marking supported on the cap
A: Logo marking on the cap surface is subject to technical evaluation. Packaging logo or labeling is supported more commonly and confirmed during order review.
