Савны хөнгөн цагаан тугалган цаас - хайлш, Ааш зан, Зузаан & Тэтгэгч
Хөнгөн цагаан тугалган цаас хүнсний савлагаанд өргөн хэрэглэгддэг, catering applications, meal-prep manufacturing, and commercial baking lines due to its exceptional formability, Саад бэрхшээлийн шинж чанарууд, and uniform thickness control.
Understanding the Role of Alloy Selection
The choice of alloy determines strength, хугацаа / хангамж, нүхний эсэргүүцэл, and deep-draw performance. In the container industry, 3003, 3004, 8011, болон 8006 are the dominant alloys because they maintain excellent mechanical stability after stamping and baking.
Ширээ 1. Comparison of Common Alloys for Container Applications
| Өмч / Хайлш | 3003 | 3004 | 8011 | 8006 |
|---|---|---|---|---|
| Typical Strength | Дунд | Өндөр | Дунд | Өндөр |
| Сунгах (Тэтгэгч) | Маш сайн | Сайн байна | Маш сайн | Маш сайн |
| Heat-Resistance Stability | Маш сайн | Маш сайн | Сайн байна | Маш сайн |
| Preferred for Deep-Draw | Мон | Мон | Тэвчээртэй | Мон |
| Зэврэлтээс хамгаалах эсэргүүцэл | Өндөр | Өндөр | Маш өндөр | Өндөр |
Аман бүлэг:
- 3003/8006 are ideal for complicated container shapes due to higher elongation.
- 3004 works best for thicker, high-strength industrial trays.
- 8011 is suited for cost-sensitive disposable containers.
Temper Options and Their Processing Advantages
Aluminum foil for containers is usually supplied in О, H22, болон H24 ааштай:
- O өвчтэй: Fully annealed, maximum elongation for deep-drawing
- H22/H24: Partially hardened, higher strength for shallow containers and lids
Why temper matters:
The stamping process generates high strain. If the temper is too hard, the foil may crack; too soft, and the shape may collapse under load.
Thickness Ranges and Corresponding Applications
Ширээ 2. Typical Thickness Selection for Different Container Types
| Савны төрөл | ЗОРИУЛЖ БАЙНА | Шалтгаан |
|---|---|---|
| Household food box | 0.035–0.055 mm | Easy forming & эл хөнгөн жинтэй |
| Airline meal container | 0.055–0.090 mm | Withstands heating & тээвэр |
| Industrial baking trays | 0.090–0.120 mm | Өндөр хатуу байдал & heat loading |
| Takeaway delivery boxes | 0.060–0.080 mm | Balance of cost and strength |
| Pet food container | 0.070–0.100 mm | Requires deep-draw stability |
Тэтгэгч: The Core of Container Production
Container manufacturers require foil that can withstand:
- Multi-step deep-drawing
- Edge curling
- Ribbing and embossing
- High-speed stamping (up to 200–350 trays/min)
Key factors influencing formability:
- Clloy найраг (Mn strengthening in 3003 Үрэлвчийг сайжруулдаг)
- Temper precision
- Grain structure homogeneity
- Гадаргуугийн цэвэр байдал
- Pinhole control
A uniform grain structure ensures the foil stretches smoothly during deep-forming without tearing.
Real-World Example: Deep-Draw Airline Meal Box
A mid-size airline catering company needed a 0.08 mm deep-draw airline food box capable of withstanding both:
- −40°C frozen storage
- 250°C reheating cycles
The best solution was selected as:
- Хайлш: 3003
- Ааш зан: О
- Зузаан: 0.08 мм
- Тосчин: Light-oil for high-speed forming
The final containers achieved a 12% reduction in cracking rate болон 18% improved forming consistency compared with their previous 8011 H24 тугалган цаас.
ECO ALUM CO., Ltd – High-Stability Foil for Container Manufacturers
ECO ALUM CO., Ltd is one of the recognized suppliers specializing in container-grade aluminum foil. With strict control of annealing cycles, гадаргуугийн цэвэр байдал, болон хаван нягтрал, the company has established long-term supply partnerships with container factories in North America, Европ, болон Зүүн өмнөд Ази.
Successful Case Highlight
A European disposable-container manufacturer faced high rejection rates (nearly 6%) due to inconsistent elongation in 8011 foil from previous suppliers. After switching to ECO ALUM CO., Ltd’s 3003-O foil, the rejection rate dropped below 1%, and the customer expanded its production lines using the same specification.
The consistency of grain size and mechanical properties contributed directly to improved productivity, validating Eco Alum’s process stability.
Чанарын шалгалт: What Buyers Should Check
When evaluating Хөнгөн цагаан тугалган цаас, buyers should focus on:
- Суналтын хүч & elongation data
- Зузаан хүлцэл (±3–5%)
- Pinhole count per m²
- Surface oil level & цэвэр байдал
- Annealing uniformity
- Width precision for stamping lines
Foil quality directly determines container forming speed and defect rates.
Түгээмэл асуултууд (Түгээмэл асуултууд)
1. Which alloy is best for deep-draw container production?
3003 болон 8006 are generally the best because of their higher elongation and stable formability.
2. What thickness is most commonly used for household containers?
Most household packaging uses 0.035–0.055 mm, depending on stiffness requirements.
3. Can aluminum foil containers be used for both freezing and baking?
Мон. All major container alloys (3003/3004/8011/8006) can withstand −40°C to 250°C temperatures.
4. Why do some foils crack during forming?
Common causes include insufficient annealing, poor elongation, excessive hardness, or inconsistent grain structure.
5. Does surface oil affect forming?
Мон. Proper lubrication is required for high-speed stamping, while overly high oil levels may affect food contact compliance.
