Scalable Metal Container Series with Uniform Diameter
Our production division manufactures a series of optimized, highly versatile cylindrical tinplate cans designed specifically for food processors implementing tiered product sizing strategies. Featuring a uniform base diameter and a height-adjustable tooling system, this series enables meat and poultry canning plants to package products of varying weight specifications—such as small, medium, and family sizes—without altering primary conveyor line configurations.
Uniform Base Dimensions: Customizable to industry standards (e.g., 52mm, 65mm, 73mm)
Height Scalability: Multi-level height ranges (covering specifications from flat sausage cans to elongated meat cans)
Substrate Properties: High-ductility electrolytic tinplate with precise hardness grading
Side-Seam Technology: High-frequency linear welding combined with a protective polymer coating strip
End Mechanism: Full-open Easy-Open End (EOE) with cut-resistant safety hem
Internal Passivation: Easy-release epoxy-amine coating / Stain-resistant organosol barrier layer
Sterilization Compliance: Supports continuous sterilization cycles under vacuum pressure up to 121°C
Application Advantages
1. Tooling Efficiency for Multi-Tiered Product Lines
Launching multi-sized product ranges (e.g., standard Vienna sausages vs. extra-large meat sausages) typically requires significant investment in factory tooling. Our uniform-diameter system eliminates this cost. By simply adjusting the can body height while maintaining a constant lid diameter, the same seaming chuck can be used across multiple packaging SKUs.
2. Advanced Non-Stick Meat Release Coating
Dense meat emulsions and sausage formulations containing active fats and high salt content are prone to adhesion. The interior of these cans is coated with an advanced thermosetting release varnish containing specialized lubricating additives. This prevents protein adhesion, ensuring the meat product retains its structural integrity when emptied.
3. Inline Protective Welded Structure
The vertical side seam of each can undergoes an advanced inline micro-welding process, immediately followed by the application of a continuous liquid or powder coating repair strip. This dual-protection measure eliminates the risk of weld cracking or micro-corrosion during the severe deformation associated with high-temperature pasteurization.
Procurement Process Overview
• Diameter and Height Selection: Standardize the can-bottom diameter while specifying the exact heights required for the target fill weights (available in three height options).
• Unified Graphic Proofing: Submit brand designs in vector format; our prepress technicians will adapt the artwork to the short, medium, and tall can templates to ensure a consistent visual style.
• Filling Line Seaming Calibration: We will send unprinted samples of each height to your engineering department to verify seaming chuck tracking and double-seam thickness tolerances.
• Automated Continuous Production: Large-scale production combines continuous side-seam welding with high-speed automated inspection technology to ensure the delivery of zero-defect product batches.
FAQ
Q1: Can the same automated seaming equipment be used for all three can heights?
A1: Yes. Since the can-opening diameter and seaming flange specifications are identical across the short, medium, and tall sizes, your production line requires only a quick, tool-free adjustment of the vertical lifting mechanism to handle the entire series, significantly reducing equipment downtime.
Q2: How does your internal coating prevent sulfide blackening caused by proteins in the sausage?
A2: Poultry and pork products release sulfur ions during high-temperature processing; these ions react with the steel to form dark iron sulfide spots. We utilize an advanced zinc-free, sulfur-resistant coating that effectively blocks these ions, keeping the interior can wall bright and clean.
Q3: What is the Minimum Order Quantity (MOQ) for the full series of can heights?
A3: To maximize production line efficiency, we generally require an MOQ of 50,000 units per height specification. However, for product series sharing the same diameter, we can offer more flexible terms during your initial market trial phase.
Q4: Do the easy-open ends feature a safety score design for retail consumers?
A4: Yes, they do. Aluminum or tinplate easy-open ends feature specially designed score depths to ensure smooth, effortless opening; additionally, a safe inward-curled edge can be customized to minimize sharp edges after opening.
