最大侧小于 2-1/8 英寸（信用卡的宽度）的任何商品均需采用聚乙烯塑料袋包装，且需在塑料袋的外侧附上条形码，以免商品放错位置或丢失。这样还可保护商品，以免其在配送过程中被撕坏或者因接触污垢、灰尘或液体而发生损坏。有些商品的尺寸可能不足以容纳标签，用袋子包装商品可确保充分扫描到条形码，又不会折叠商品的边缘处。

Packaging Small Products
On this page, you will learn how to properly prep products that are smaller than a credit card to protect them from dust or damage throughout the fulfillment process.
Important: Failure to comply with FBA product preparation requirements, safety requirements, and product restrictions may result in the refusal of inventory at the Amazon fulfillment center, disposal or return of inventory, blocking of future shipments to the fulfillment center, or charging for preparation or for noncompliance at the fulfillment center.
Any product whose largest side is less than 2-1/8" (the width of a credit card) needs to be packaged in a poly bag with the barcode on the outside of the bag to prevent the Unit from being misplaced or lost. This will also protect the unit from damage by tearing, dirt, dust or liquid during the fulfillment process. Some products may not be large enough to accommodate a label, and bagging the unit will allow the barcode to be fully scannable without wrapping over the edges of the product.
