5 Key Factors When Selecting Empty Food Cans

Memilih empty food cans dictates shelf life and unit economics. Whether sourcing for sauces or pressurized oils, precise packaging engineering directly impacts your bottom line.

Material Choice: pelat timah, Stainless Steel or Composite Options

Saat mencari sumber empty food cans, align material properties with your specific product chemistry.

1. Inti Sifat bahan
   • pelat timah
     • Tipis Baja basis (Double-Reduced for higher yield, reducing weight by up to 30% while maintaining 400N+ strength)
     • Kuat Ketahanan korosi via controlled tin coating
     • Cost-effective for high-volume ambient foods
   • Baja Tahan Karat
     • Maximum structural strength (316L grade extends high-acid food shelf life past 36 bulan)
     • Superior rust immunity
     • Essential for highly acidic or saline environments
   • Gabungan
     • Multi-layer structure targeting low OTR (Tingkat Transmisi Oksigen)
     • Enhanced barrier control
     • Ringan, rigid alternative
2. Perbandingan kinerja

For scaling brands, FANXUN recommends aligning Ketahanan korosi strictly with product pH to avoid over-engineering packaging spend.

Matching Can Dimensions & Specifications to Your Fill Volume

Tepat Ukuran Dan Spesifikasi dictate fill accuracy and seam integrity. A 0.02mm wall thickness reduction across a 1-million unit run saves approximately 1.5 metric tons of metal.

1. Perencanaan kapasitas
   • Confirm specific Product volume and density
   • Match internal Diameter to filling nozzles
   • Menyesuaikan Tinggi to ensure safe thermal expansion headspace
2. Technical alignment
   • Validate wall thickness against retort pressure parameters
   • Verify seaming tolerance with specific lid/end profiles
   • Confirm axial load capacity for palletized transport
3. Quick sizing checklist
   1. Define net Kapasitas
   2. Select standard Ukuran kaleng (misalnya, 300×407)
   3. Validate seam overlap tolerances
   4. Run pilot filling and sterilization tests

Manufacturing Process Impact: Menggambar Dalam vs. Ekstrusi Dampak

The chosen Proses manufaktur dictates structural limits and economics.

1. Gambar yang dalam
   • Utilizes Draw-Redraw (DRD) for seamless Kaleng dua potong
   • Soudronic wire welding supports standard Kaleng tiga potong
   • Optimal for sheet forming efficiency
2. Ekstrusi dampak
   • Forms seamless monobloc bodies
   • Guarantees uniform wall thickness
   • Achieves burst pressures exceeding 18 batang (260 psi)
3. Production decision path
   • Low internal pressure/retort foods → deep drawing
   • High-pressure/food aerosols → impact extrusion
   • Premium aesthetic demands → seamless finish

Di dalam 2025, Smithers melaporkan:

“Metal food packaging continues to grow steadily, driven by recyclability and long-term barrier performance,” noting sustained demand through 2028.

Perawatan Permukaan: Pernis Internal, Epoxy Lining and More

Internal chemistry prevents metal migration; external coatings protect brand equity.

   • Sesuai dengan FDA, BPA-IN Linings (projected to dominate 85% dari 2026 pasar)
   • Ditargetkan Barrier control against sulfidation
2. External defense
   • Anti karat Pelapis
   • Zero-VOC, UV-resistant print varnish
   • High-slip, scratch-resistant finishes for conveyor efficiency
3. Application flow
   1. Clean and treat base metal
   2. Apply uniform primer
   3. Cure at strict temperature parameters
   4. Inspect cross-hatch adhesion

Ensuring Quality Control: Pengujian Kebocoran, Kepatuhan FDA, Standar ISO

Rigorous QC keeps compromised empty food cans off retail shelves.

1. Mechanical validation
   • Helium Pengujian kebocoran (detecting micro-leaks as small as 1×10⁻⁷ mbar·L/s)
   • Burst pressure trials
   • Destructive seam tear-down inspection
2. Penyelarasan regulasi
   • Ketat kepatuhan FDA
   • standar ISO (misalnya, ISO 9001:2008)
   • Verified Material Sertifikasi
   • Routine in-line Inspeksi
3. Control workflow
   • Incoming steel gauge audit
   • Sejalan 100% pengujian tekanan
