Come calcolare il risparmio sul costo per unità della carta glassine

计算玻璃纸每单位成本（CPU）节省涉及将您当前的玻璃纸解决方案的成本与建议的替代解决方案（新供应商、不同规格、替代材料）进行逐单位比较（例如，每袋、每张、每平方米）。以下是逐步指南：
Core Formula:
CPU Savings = 当前 CPU - 提议 CPU
Percentage Savings = [(当前 CPU - 提议 CPU) / 当前 CPU] * 100%
Steps to Calculate:
1. 定义“单位”：
2. 计算当前玻璃纸 CPU:
3. 计算建议的玻璃纸（或替代品）CPU：
4. 计算储蓄：
- Savings per Unit = 当前 CPU - 提议 CPU
- Percentage Savings = [(当前 CPU - 提议 CPU) / 当前 CPU] * 100%
Example Calculation (Per Finished Envelope):
1. 当前玻璃纸:
- Roll Cost: $500
- Usable Envelopes per Roll: 5,000
- Material Cost per Envelope: $500 / 5,000 = $0.10
- Conversion Cost per Envelope: $0.05 (calculated separately)
- Current CPU = $0.10 + $0.05 = $0.15 per envelope
2. 提议的玻璃纸：
- Roll Cost: $475
- Usable Envelopes per Roll: 4,900 (轻微的处理差异导致产量略低)
- Material Cost per Envelope: $475 / 4,900 ≈ $0.0969
- Conversion Cost per Envelope: $0.05 (Assumed same for simplicity)
- Proposed CPU = $0.0969 + $0.05 = $0.1469 per envelope
3. 储蓄:
关键考虑因素与因素：
- Volume: Does the new price depend on order volume? Calculate CPU at your typical order volume.
- Minimum Order Quantities (MOQs): Higher MOQs might lock up capital or increase storage costs.
- Quality & Performance: Does the cheaper option meet all technical requirements (barrier properties, strength, printability, heat sealability, regulatory compliance)? A failure here can cost far more than any material saving (returns, scrap, lost production, reputational damage).
- Supplier Reliability: A cheaper supplier with poor delivery performance can cause costly production delays.
- Waste & Yield: 如示例所示，即使是转换率的小变化也会显著影响有效CPU。这常常被忽视！
- Hidden Costs: Factor in costs like:
- Testing/validation of new material (especially critical in Pharma/Food).
- Potential machine adjustments/downtime during changeover.
- Inventory carrying costs.
- Tooling changes (if needed for new thickness/coating).
- Total Cost of Ownership (TCO): 为了获得最准确的图景，请考虑在使用材料的整个生命周期内的所有成本，而不仅仅是即时购买价格和转换费用。
- Alternative Materials: If comparing Glassine to polymer films or coated papers:
- Ensure functional equivalence.
- Carefully evaluate differences in conversion processes, speeds, waste, and performance in the final application.
- Consider end-of-life/recyclability if relevant to your brand/customers.
In Summary:
为了准确计算 Glassine CPU 节省，仔细收集您当前和提议解决方案的成本数据（材料和转换），重点关注相同的明确定义单位（最好是成品）。至关重要的是，考虑产量、废料和潜在质量/性能风险的差异。简单的 CPU 相减给出了直接的节省，但真正的价值来自于理解对您运营的整体影响。在承诺之前，始终彻底验证新材料。
