A practical guide from the factory floor — what actually protects bananas over a 30-day refrigerated sea voyage.来自生产一线的实用指南——30天冷藏海运中真正保护香蕉的关键细节。
Bananas are among the most demanding fruits to pack: they are shipped green, respire heavily, bruise easily, and spend up to 30 days in a refrigerated container at 13–14 °C and 90 %+ humidity. The carton is not just a box — it is a structural, ventilated, moisture-resistant component of the cold chain. Here is what we check on every banana carton order across our plants in China, Vietnam and the Philippines.
The global standard is the 13 kg (28.6 lb) telescopic carton, roughly 500 × 400 × 244 mm, which stacks 48 boxes per pallet layer pattern in a 40' reefer. Middle East and some Asian markets prefer the 18 kg format. Both consist of a lid, a bottom tray, and often an internal pad. If your buyer has not specified, ask which supermarket program the fruit is destined for — the retailer usually dictates the format.
A banana carton at the bottom of a reefer stack carries over 200 kg for a month in near-saturated humidity, which can halve the compression strength of ordinary board. That is why most export banana cartons use BC double-wall (5-ply) construction with wet-strength (WS) or semi-wet-strength liners. Ask your supplier for the BCT (box compression test) value at 90 % relative humidity, not just the dry figure. Fuxing Group produces A/B/C/E flute combinations in 3, 5 and 7 ply and tests compression in-house.
Ventilation holes must align vertically through the whole pallet so forced-air cooling can pull air through the fruit. Typical designs use 4–6 side vents plus hand holes that double as airflow paths. Poor vent alignment is one of the most common causes of arrival ripening claims. We die-cut vents to match the pallet pattern of your specific stacking program.
Condensation is unavoidable when a container door opens in a tropical port. Wet-strength resin liners, or a light wax/water-based barrier coating, keep the board from softening. Full wax dipping is now rare (it blocks recycling in many markets) — modern water-based coatings achieve similar protection and remain recyclable, which matters for EU and Japanese retail programs.
Banana cartons are the most visible branding surface in a wholesale market. High-graphics flexo printing (up to 4 colors) with GMI-certified quality control keeps brand colors consistent across production runs — we hold GMI certification for direct-print corrugate and print programs for brands such as Del Monte, Unifrutti and S&W.

香蕉是最考验包装的水果之一:青果装运、呼吸旺盛、极易碰伤,还要在13–14℃、湿度90%以上的冷藏集装箱里漂30天。香蕉箱不只是一个纸箱,而是冷链系统中承重、通风、防潮的结构件。以下是我们中国、越南、菲律宾工厂每一张香蕉箱订单都要过的检查项。
全球主流是13kg(28.6磅)天地盖箱型,外尺寸约500×400×244mm,40尺冷柜标准码盘。中东及部分亚洲市场偏好18kg箱型。具体选哪种,通常由终端超市的采购规范决定——下单前先问清楚水果的销售渠道。
冷柜底层的香蕉箱要在接近饱和的湿度下承受200公斤以上压力整整一个月,普通纸板的抗压强度在高湿下会腰斩。所以出口香蕉箱主流采用BC双瓦楞(5层)结构加湿强(WS)挂面纸。向供应商索要90%相对湿度下的BCT抗压值,而不是干燥实验室数据。复星集团可生产A/B/C/E楞3/5/7层组合,并有自检抗压测试。
通风孔必须在整个托盘堆码中上下对齐,冷风才能贯穿果体强制降温。常见设计为4–6个侧孔加兼作风道的手提孔。通风孔错位是到港催熟索赔最常见的原因之一。我们按客户具体的码盘方案模切对位通风孔。
热带港口开柜瞬间的冷凝水无法避免。湿强树脂挂面或水性防潮涂布能防止纸板吸潮变软。整箱浸蜡工艺因妨碍回收已逐渐被淘汰——现代水性涂布防护相当且可回收,这对欧盟和日本商超体系尤其重要。
在批发市场,香蕉箱是品牌曝光度最高的载体。柔印4色配合GMI认证的色彩管理,保证每一批箱子品牌色一致。我们持有GMI瓦楞直印认证,为Del Monte、Unifrutti、S&W等品牌代印。查看全部香蕉箱产品。
