| Base Material | Most air bubble wrap is made from polyethylene film, commonly LDPE or a blend containing LLDPE. | Confirm the polymer type, film construction, and whether additives or laminates are present. | Single-polymer polyethylene is generally easier to identify, document, and route through compatible recycling systems. | Prefer clear material disclosure |
| Film Thickness | Common film thicknesses are approximately 50–200 microns. Heavy-duty grades may be thicker. | Check the measured thickness in microns and request a tolerance range rather than relying only on product descriptions such as “light” or “heavy.” | Thicker film can improve puncture resistance but increases packaging weight, volume, and material use. | Match thickness to product risk |
| Bubble Diameter | Small bubbles are often around 6–10 mm; larger cushioning bubbles may be approximately 19–25 mm. | Verify bubble diameter, bubble height, spacing, and whether the bubbles remain inflated after compression. | Larger bubbles can provide greater cushioning, while smaller bubbles may be more suitable for surface protection and compact packing. | Select by fragility and box space |
| Puncture and Tear Resistance | Performance varies with resin formulation, thickness, bubble size, and manufacturing quality. There is no universal value for all grades. | Request test results using recognized methods, such as Elmendorf tear, puncture, tensile, or impact testing, where relevant. | Higher resistance reduces the risk of package failure during handling, palletization, and container movement. | Require lot or grade-specific test data |
| Cushioning Performance | Cushioning depends on bubble height, compression behavior, load, temperature, and storage time. | Check compression resistance and recovery after repeated loading, especially for fragile or high-value goods. | Packaging that loses air or flattens under load may provide insufficient protection during long-distance transit. | Test under expected shipping loads |
| Temperature Range | Polyethylene performance changes with temperature; cold conditions can reduce flexibility and heat can accelerate deformation. | Ask for storage and operating guidance from the supplier and test the packed product in expected climate conditions. | Global shipments may experience refrigerated warehouses, hot containers, direct sunlight, or large temperature changes. | Validate for route conditions |
| Recycled Content | Recycled content may range from 0% to a declared percentage, depending on the product specification and supply chain. | Request a written recycled-content declaration and determine whether the percentage is pre-consumer, post-consumer, or a mixture. | Declared content can support sustainability reporting, but it should not be assumed without supplier documentation. | Verify with documentation |
| Recyclability | Clean polyethylene film may be accepted by some flexible-plastic recycling programs, but collection availability differs by country and municipality. | Check local acceptance rules, contamination limits, and whether the film must be delivered to a dedicated film-recycling collection point. | Recyclable in theory does not guarantee that the material can be recycled at the destination. | Confirm destination infrastructure |
| Material Simplicity | Unlaminated, mono-material polyethylene is generally simpler to identify and process than multi-layer or foil-laminated packaging. | Look for coatings, adhesive layers, paper backing, metallized films, or other materials that may complicate recycling. | Simple construction can reduce disposal confusion and improve end-of-life handling across multiple markets. | Prefer mono-material construction |
| Packaging-to-Product Ratio | The suitable amount of wrap depends on product fragility, shape, clearance inside the carton, and expected handling severity. | Measure packed dimensions and weight, then compare damage rates and material consumption through a packing trial. | Excess packaging increases dimensional weight, freight cost, storage space, and waste without necessarily improving protection. | Optimize through drop and vibration tests |
| Customs Product Description | Describe the item accurately as polyethylene air bubble protective packaging or a similar clear commercial description. | Use a consistent description across the commercial invoice, packing list, purchase documents, and shipping instructions. | Clear descriptions help reduce questions caused by vague terms such as “plastic material” or “packing supplies.” | Use specific, consistent wording |
| HS Classification | Plastic packing articles are commonly considered under HS heading 3923, but the correct subheading depends on the product form and importing country. | Confirm the applicable national tariff subheading with the importer, customs broker, or customs authority before shipment. | Incorrect classification can cause delays, duty corrections, penalties, or requests for additional technical information. | Confirm destination-specific code |
| Country of Origin | The origin is generally based on where the product was manufactured or underwent the legally relevant substantial transformation. | Keep the manufacturer’s origin statement and ensure the country of origin marking meets destination rules. | Origin can affect duty treatment, trade measures, reporting obligations, and customs documentation. | Document and mark accurately |
| Commercial Invoice Data | Typical details include product description, quantity, unit value, total value, currency, country of origin, Incoterms, and buyer or seller information. | Ensure the invoice value reflects the actual transaction or legally accepted customs value and matches the shipping documents. | Incomplete or inconsistent invoice data is a common cause of customs queries and clearance delays. | Use complete and matching records |
| Packing List Data | Include roll or carton quantity, net weight, gross weight, package dimensions, and package marks where applicable. | Reconcile the packing list with the commercial invoice and transport document before dispatch. | Accurate package information supports inspection, freight calculation, warehouse receiving, and customs verification. | Check quantity and weight accuracy |
| Regulatory Claims | Terms such as “recyclable,” “recycled,” “compostable,” or “eco-friendly” may be subject to local advertising and environmental-claim rules. | Retain supporting evidence and avoid unsupported claims, especially when selling or importing into multiple jurisdictions. | Unsubstantiated environmental claims can create compliance, labeling, or commercial risks. | Substantiate every environmental claim |
| Supplier Quality Control | Useful controls include incoming material checks, thickness measurement, bubble-size inspection, seal integrity testing, and batch traceability. | Request a quality specification, inspection record, certificate of analysis, or batch identification system where appropriate. | Consistent quality is especially important when the same packaging is shipped through different climates and logistics networks. | Buy against a written specification |
