Product Introductions
The 16oz Clear Plastic Containers with Lids are manufactured using a one-piece injection molding process. The raw materials consist of food-contact-grade PET/PP plastic granules, which undergo rigorous testing for moisture content and melt flow stability prior to production to ensure that no issues-such as air bubbles or shrinkage deformation-arise during the subsequent injection molding phase. During the mold design stage, the entire container body was engineered with uniform wall thickness to ensure that both transparency and structural integrity remain consistent throughout mass production.
This model is primarily utilized for packaging spices, dry goods, and food-grade powdered products. Prior to factory shipment, random assembly tests are routinely conducted to simulate real-world usage scenarios-specifically lid-tightening and inversion tests-thereby minimizing the likelihood of loose lids or powder leakage occurring during subsequent customer storage or transportation. The entire production workflow has been standardized into a fixed operational protocol, making it ideally suited to meet the demands of bulk purchasing requirements that necessitate a long-term, stable supply.

Product Features
The food-grade plastic material, suitable for dry food storage, undergoes rigorous quality control from raw material sourcing through to the final product's dispatch. Every production batch is subjected to tests for melt flow index and color stability to ensure consistent material performance across different manufacturing cycles. Following injection molding, the transparent bottle bodies enter a temperature-controlled cooling phase to stabilize their molecular structure, thereby guaranteeing that they remain resistant to clouding or deformation during long-term use.
The transparent bottle body-designed to facilitate quick identification of contents-is achieved through a mold mirror-polishing process. Since this step directly impacts the finished product's light transmittance and visual clarity, our mold maintenance protocol includes regular polishing of the mold cavities and cleaning of the runners to prevent minute scratches from compromising the overall aesthetic appeal.
Compatibility with labeling and branding applications is a structural feature integrated during the design phase. The bottle body features a designated, relatively flat surface area for labeling, facilitating both automated and manual application while preventing issues such as label peeling or air bubbles.
The tight-sealing lid structure, designed for effective moisture control, undergoes individual spot-checks during the production assembly stage. By simulating the vibrations and inverted positioning typical of transit conditions, we verify the tightness of the screw threads and the proper seating of the sealing ring, thereby minimizing the risk of moisture ingress during actual use.
Production workflows-optimized for both retail packaging and bulk distribution-are managed via standardized assembly lines to support continuous, high-volume shipments. Furthermore, during the packing stage, a layered separation method is employed to minimize friction and prevent surface scratches during transit.
Support for OEM customization-tailored to meet diverse market needs-is primarily enabled by the modular and scalable design of our molds. Features such as lid color, logo placement, and packaging configuration can be flexibly adjusted without requiring modifications to the core bottle mold, allowing us to effectively meet the specific sales requirements of various market channels.

Why Choose Us
The 16oz Clear Plastic Container with Lid Manufacturer is a standard injection-molded product at our facility, characterized by its long-term, stable mass production status. Manufactured using food-grade plastic resins, the material undergoes a centralized drying process before entering the injection molding stage, where the bottle body and neck are integrally formed under strictly controlled process parameters. Our production process is grounded in standardized mold management, ensuring consistency across different batches regarding dimensions, clarity, and the precision of the screw threads. This specific model is typically integrated into our routine production schedule, leveraging continuous production lines to minimize mold changeovers and enhance the reliability of delivery for bulk orders.
In terms of supply partnerships, we operate on a direct-from-factory model and support OEM/ODM customization-including variations in lid color, logo printing, and outer packaging solutions-to meet the diverse requirements of various market channels. Our production system features inherent capacity flexibility, allowing us to adjust production schedules according to order volume while maintaining product consistency through multi-stage quality control. For export operations, we are fully equipped to comply with the regulatory requirements and documentation standards of various international markets, offering wholesalers and distribution channels flexible ordering and delivery options to accommodate their long-term, stable procurement needs.
Sampling Policy
During the sampling phase for the 16oz Clear Plastic Containers with Lids Wholesales, we typically adhere to the standard protocols used for our official mass-production molds. Upon receiving a sample request, our factory prioritizes utilizing existing molds for trial runs to ensure that the samples-and the subsequent bulk production-maintain absolute consistency in terms of structural dimensions, neck threading, and sealing integrity. The sample production process involves calibrating our injection molding machinery to match the exact parameters used for mass production-including material temperature, holding pressure duration, and cooling cycles-thereby accurately replicating actual production conditions and preventing any discrepancies between the samples and the final bulk shipment.
Providing "Samples available before bulk order confirmation" is an integral part of our standard business workflow. For products utilizing standard molds-such as the SN-49-we can provide either stock samples or samples closely representative of mass-production quality within a relatively short timeframe. In cases involving custom requirements-such as specific logos, colors, or structural modifications-we conduct a fresh sampling assessment; once the proposed modifications are confirmed, we perform a new mold trial to validate the design. Sample fees are typically eligible for partial or full reimbursement against subsequent bulk orders, thereby supporting our clients in conducting necessary market testing and final verification prior to committing to a formal mass purchase.
FAQ
Q: Do you offer product customization services?
A: Yes, we provide OEM/ODM services, including logo printing, packaging design, and partial structural or functional modifications. Customization requires design confirmation and sample approval in advance.
Q:How is product quality ensured?
A: We follow strict production processes and quality management systems. Each batch undergoes factory inspection to ensure compliance with specifications, functionality, and safety standards. Third-party quality inspection reports can also be provided upon request.
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:How do you ensure quality consistency across repeated orders?
A: Production follows standardized processes, and key dimensions and materials remain consistent for repeat orders.
