2.1 ตารางองค์ประกอบทางเคมี

2.2 Key Mechanical Property Parameters

These balanced mechanical parameters allow the 0.013mm ultra-thin foil to resist cracking or breaking during high-speed lamination, vacuum forming, and folding/sealing processes, ensuring strong batch-to-batch production stability and meeting the precision processing needs of specialty coffee packaging.

III. Core Value of O-Temper Annealing Process

โอ-อารมณ์ (fully annealed soft state) is the optimal process condition for coffee packaging foil. High-temperature uniform annealing releases internal stresses, bringing the foil to its softest, most ductile state. This directly addresses three major pain points in coffee packaging production:

1. Fold & ความต้านทานการแตกร้าว, Stable Barrier

No micro-cracks develop during gusset forming, bag bottom shaping, or vacuum pressing, completely avoiding barrier failure due to damage, thereby preserving coffee flavor long-term.

2. Excellent Conformity, Prevents Delamination

The soft temper adapts exceptionally well, bonding tightly and smoothly with various films and papers, eliminating bubbles or wrinkles and significantly reducing delamination risks during storage and transport.

3. Suited for High-Speed Production, High Yield

Stable running tension with minimal springback ensures stress concentration doesn’t occur at heat seals, resulting in flat, tight seals. Ideal for high-speed printing, เคลือบ, and pouch-making lines.

IV. Logic Behind the 0.013mm “Golden Thickness” การคัดเลือก

1. Avoids Drawbacks of Thicker Foil

Thicker foils increase package weight and raw material costs while making the pouch feel stiff and cheap, conflicting with the lightweight, premium aesthetic of specialty coffee.

2. Avoids Quality Risks of Thinner Foil

Ultra-thin foils (9–10μm) have very low process tolerance, leading to a sharp increase in pinhole rates. This creates high risks of hidden oxygen/moisture ingress, causing premature oxidation, flavor degradation, and high after-sales risk.

3. Achieves Tri-Dimensional Value Balance

The 0.013mm specification hits the perfect balance between barrier reliability, เสถียรภาพการผลิต, และความคุ้มค่า, making it the most cost-efficient choice for high-end coffee packaging.
