Mini Plastic Spice Bottle With Cap

Product Introductions

 

The Mini Plastic Spice Bottle With Cap is manufactured in our facility as a compact seasoning container for retail filling lines, food service repacking, and private label spice projects. With a size of 41×58mm and a 68ml capacity, this model is proportioned for fine powders and granulated seasonings where stable stacking, controlled dispensing, and efficient shelf use are required. The structure is designed with practical filling and transport considerations in mind, ensuring compatibility with common manual and semi-automatic packing processes.

Production is carried out through precision injection molding using food-grade plastic resin. During manufacturing, we monitor material drying parameters, injection pressure, and cooling cycles to maintain consistent wall thickness and neck accuracy. The mold cavity is regularly maintained to control thread tolerance and cap engagement stability. Each batch undergoes dimensional sampling and cap fitting verification before packing, ensuring uniform specification and dependable bulk supply for export orders.

For the Mini Plastic Spice Bottle With Cap, quality control is integrated into each stage of production rather than limited to final inspection. Incoming raw materials are first verified against purchase specifications, including resin grade confirmation and appearance checks before drying and feeding into the injection system. During molding, operators conduct in-process dimensional measurements at defined intervals, focusing on bottle height, outer diameter, neck inner diameter, and thread depth to ensure the mold cavity remains within tolerance.

Thread matching inspection is carried out by pairing bottles and caps from the same production batch to confirm smooth engagement and proper torque performance. In addition, leak test sampling is performed under simulated vibration and inverted storage conditions to assess sealing stability for fine powder applications. Before packing, a final visual inspection is conducted to remove pieces with surface defects, deformation, or contamination. The inspection ratio is determined based on total batch volume and production stability records. If required, third-party inspection such as SGS, BV, or a customer-appointed agency can be arranged prior to shipment, and the production lot will be reserved until inspection clearance is completed.

The Mini Plastic Spice Bottle With Cap follows a structured production and delivery schedule based on confirmed order specifications and manufacturing capacity. Sample lead time is normally 3–7 working days, as samples are arranged directly from current mold production or small-batch trial runs. For standard bulk orders, the production lead time is typically 15–25 days after deposit receipt and final artwork confirmation. During this period, raw material preparation, color matching (if required), injection molding scheduling, and packing allocation are arranged in sequence. For customized color orders, additional time may be required to prepare masterbatch, clean the injection system, and stabilize color consistency before mass production begins.

Before accepting any order, we confirm the production schedule according to existing mold allocation, machine loading rate, and order quantity. The injection cycle time, cooling time, and post-molding inspection capacity are calculated to ensure realistic delivery planning. Once production is scheduled, material procurement, molding, inspection, and packing are executed according to the confirmed timeline. This approach allows us to maintain predictable lead times while avoiding overcommitment beyond actual factory capacity.

For the Plastic Spice Bottle Manufacturer, customization work is arranged directly within our production workflow to ensure consistency between approved samples and bulk output. Bottle color adjustment is achieved by controlling the ratio of masterbatch during material mixing, with test shots conducted to stabilize shade and transparency before formal production. Cap color selection follows the same process, and color matching can be referenced to Pantone standards or physical samples provided by the customer. During injection, parameters such as temperature and back pressure are fine-tuned to maintain uniform pigment dispersion and avoid color streaking.

Silk screen logo printing is completed after molding and surface cleaning, with printing fixtures designed specifically for this bottle size to ensure alignment accuracy and repeatable positioning. For label application orders, we verify surface tension and adhesion performance before mass labeling to prevent lifting during storage. Outer carton customization, including printed marks, barcodes, and shipping instructions, is arranged according to export requirements. Artwork confirmation is required prior to production scheduling, and pre-production samples are prepared for approval to ensure that color, printing placement, and overall presentation meet the confirmed specification before proceeding to bulk manufacturing.
