Who This Is For
If your team loads pallets daily or ships to distribution centers, packaging decisions directly impact damage rates and transit costs. Stretch film — also called pallet wrap — is the most widely used secondary packaging material globally.
Many buyers select rolls based on price alone, leading to breakage and poor load retention. This guide helps you evaluate specifications and choose a film that balances performance with total cost of ownership.

The Recommended Product: Cast LLDPE Stretch Film
Xiahong Packaging manufactures cast LLDPE stretch film for industrial applications. Cast film is produced by extruding molten resin through a flat die onto a chilled roll, delivering clear transparency, consistent thickness, and high initial tack — key attributes for pallet wrapping.
PCR-blended stretch film is also available, reducing virgin plastic consumption without compromising load-holding performance.
Key Specifications
| Specification | Details |
|---|---|
| Material | Cast LLDPE (virgin or PCR blend) |
| Thickness | 0.75 mil, 0.80 mil, 0.90 mil, 1.0 mil, 1.25 mil |
| Width | 12"–60" (custom widths available) |
| Core Size | 1" or 3" cardboard core |
| Roll Length | 1,500–3,000 ft per roll |
| Color | Clear (standard), black, white, blue, red, yellow |
| Cling | Single-sided or double-sided |
| Ply | Single, 2-ply, 3-ply (co-extruded) |
| Temperature Range | -20°F to 140°F |
| MOQ | Contact sales for volume pricing |
Performance Highlights
- Prewrapped rolls offer up to 250% stretch ratio, reducing film consumption per pallet by 20–30%
- High puncture resistance protects against sharp corners and rough pallets
- UV-stabilized options for outdoor storage
- High tear propagation resistance prevents small punctures from escalating

Why Cast LLDPE Outperforms Alternatives
1. Clear Load Visibility
Clear cast film lets forklift operators identify pallet contents at a glance without unwrapping, cutting handling time during sorting and inventory.
2. Consistent Gauge and Mechanical Properties
Cast extrusion delivers tighter thickness tolerance (±8%) versus blow film (±12–15%). Uniform gauge ensures predictable stretch and reliable load retention during transit.
3. High Initial Tack
Strong initial tack grips the first pallet layer, creating a self-locking effect as wraps overlap. Mechanical tension holds loads through vibrations and handling shocks in ocean and land freight.
4. Consumption-Based Cost Savings
Premium pre-stretched film delivers more coverage per roll. When 0.80 mil film stretches to 2.0 mil during application, effective coverage increases significantly — lowering cost per pallet wrapped.
---
Ideal Applications
| Application | Recommended Thickness | Key Consideration |
|---|---|---|
| Standard pallet loads | 0.80–0.90 mil | Hand wrap or semi-auto machine |
| Heavy industrial goods | 1.0–1.25 mil | 3-ply for puncture resistance |
| Food and beverage | 0.80–1.0 mil | Food-contact-safe resin available |
| Outdoor or ocean freight | 1.0+ mil UV-stabilized | UV film prevents degradation |
| Lightweight e-commerce | 0.75 mil prewrapped | Maximizes coverage, lowers cost per roll |
---
Verification Checklist
Before committing to a stretch film purchase:
- Actual gauge: Measure a sample — nominal may differ from actual by 5–10%
- Stretch ratio: Confirm pre-stretch percentage (200–300% for prewrapped rolls)
- Cling type: Single-sided or double-sided — double-sided may be unnecessary
- Tension consistency: Ask if the supplier tests cone-to-cone tension
- PCR certification: Request documentation and verify percentage on data sheet
- Core integrity: Confirm load rating — weak cores collapse on automated wrappers

目标读者
如果您的团队每天装载托盘或将成品发往配送中心，包装决策将直接影响破损率和运输成本。缠绕膜（又称托盘包装膜）是全球供应链中使用最广泛的二级包装材料。
许多买家将其视为普通商品，仅凭价格选择。这会导致薄膜破裂和负载固定不足。本指南帮助您评估规格，选择兼顾性能与总拥有成本的产品。

推荐产品：流延 LLDPE 拉伸膜
夏宏包装生产用于工业应用的流延线性低密度聚乙烯（LLDPE）拉伸膜。流延膜通过将熔融树脂经平模头挤出到冷却辊上制成，具有透明度高、厚度均匀和初粘性强的特点——这些都是托盘缠绕和货运固定的关键特性。
夏宏还提供PCR混合拉伸膜，在性能不妥协的前提下减少原生塑料消耗。
主要规格
| 规格 | 详情 |
|---|---|
| 材质 | 流延 LLDPE（原生或 PCR 混合） |
| 厚度 | 0.75 mil、0.80 mil、0.90 mil、1.0 mil、1.25 mil |
| 宽度 | 12"–60"（可定制宽度） |
| 纸管内径 | 1英寸或3英寸 |
| 卷长 | 每卷 1,500–3,000 英尺 |
| 颜色 | 透明（标准）、黑色、白色、蓝色、红色、黄色 |
| 自粘层 | 单面自粘或双面自粘 |
| 层数 | 单层、双层、三层（共挤） |
| 耐温范围 | -20°F 至 140°F |
| 最小起订量 | 请咨询销售获取批量价格 |
性能亮点
- 预拉伸卷提供高达 250% 拉伸比，每托盘薄膜消耗量减少 20–30%
- 高抗穿刺性保护尖锐棱角和粗糙托盘
- 提供抗紫外线选项适用于户外存储
- 高抗撕裂扩展性防止小穿刺演变为全长撕裂

为什么流延 LLDPE 优于替代品
1. 清晰的负载可见性
透明流延膜让叉车操作员在不拆包的情况下一目了然地识别托盘内容物，减少分拣和盘点时间。
2. 均匀的厚度和机械性能
流延挤出厚度公差更严格（±8%），优于吹膜（±12–15%）。均匀厚度确保可预测的拉伸和运输中可靠的负载固定。
3. 高初粘性
强劲初粘性紧抓托盘第一层，后续缠绕形成自锁效果。机械张力通过海运和陆运的振动和装卸冲击保持负载完整。
4. 基于消耗的节省
优质预拉伸膜每卷提供更高覆盖量。0.80 mil 膜在应用中拉伸至 2.0 mil 时，有效覆盖量显著增加——降低每托盘成本。
---
理想应用场景
| 应用 | 推荐厚度 | 关键考虑 |
|---|---|---|
| 标准托盘负载 | 0.80–0.90 mil | 手动或半自动缠绕机 |
| 重工业货物 | 1.0–1.25 mil | 三层抗穿刺 |
| 食品饮料 | 0.80–1.0 mil | 可选食品接触级树脂 |
| 户外或海运 | 1.0+ mil 抗紫外线 | 抗紫外线膜防降解 |
| 轻量电商 | 0.75 mil 预拉伸 | 最大化覆盖量，降低每卷成本 |

验证清单
采购前向供应商验证：
- 实际厚度： 用千分尺测量样品——标称可能与实际相差 5–10%
- 拉伸比： 确认预拉伸百分比（预拉伸卷应为 200–300%）
- 自粘类型： 单面或双面——双面有时不必要
- 张力一致性： 询问供应商是否测试锥到锥张力均匀性
- PCR 认证： 索取文档并在产品数据表上验证百分比
