Reusable produce and bulk bin bags: what to buy and how to weigh them

Elle Marchetti · Published July 27, 2026

购物袋重量的问题

生鲜食材通常按重量计价，因此较重的环保袋会在每次结账时增加额外费用。目前市场上出色的生鲜果蔬袋单个重量仅约 10–15g——相比一公斤苹果的重量几乎可以忽略不计。而较便宜的厚帆布袋重量可达 40–80g，装满一整车购物车时累积的重量相当可观。

在自助结账机前，大多数澳大利亚超市都有一个“Reusable Bag”（环保袋）按键，能自动扣除约 5–7g 的皮重。如果你的袋子更重，可以先称重一次，用衣物标记笔把数字写在袋子上，结账时直接输入即可。

网眼袋 vs 细棉布袋 vs 梭织棉袋

网眼袋（尼龙或再生聚酯）

最适合超市果蔬。收银员隔着网眼就能看清袋内物品（无需拿出），可直接透过网眼称重，洗涤后易干。缺点：无法在报废后彻底降解/堆肥；清洗 100 次后边缘可能会磨损散线。

细棉布袋

最适合散装面粉、大米、白糖和香料。精细的织法可防止面粉扬尘飞出。自带抽绳方便收口。可生物降解/堆肥。缺点：看不见袋内物品，且沾水后较重。

梭织棉袋（Onya 风格）

最适合散装谷物和意大利面。比细棉布更结实耐用，支持机洗。缺点：空袋皮重较重（约 20–30g）。

什么是“皮重”（Tare）

皮重（Tare）指的是空容器的重量。澳大利亚的大多数散装食品店（如 The Source、Naked Foods、Terra Madre、Wray Organic）都会在你装货前在前台称量袋子的皮重，并在结账时扣除该重量。有些店家会打印皮重贴纸；有些则会用标记笔直接写在袋子上。

在超市的散装区（如 Woolworths、IGA），并没有正式的去皮流程——建议使用你手头最轻的袋子，接受这几克的微小误差。

如何选择合适的尺寸

  • 小号（25×20cm） — 蘑菇、坚果、零食、香料。
  • 中号（30×35cm） — 苹果、橙子、土豆、大部分散装谷物。
  • 大号（40×50cm） — 绿叶蔬菜、芹菜、花菜、2kg 面粉。

一套 4 个中号加上 2 个小号袋子就能满足每周大部分的采购需求。

保养与护理

  • 如果装过带水汽或叶菜类食材，建议每次使用后进行清洗。
  • 机洗时放入洗衣网袋中（以保护抽绳不受损）。
  • 悬挂晾干（烘干机的高温可能会使棉袋缩水并让果汁污渍固定在布料上）。
  • 当抽绳或缝线损坏时进行更换——通常可使用 2–3 年。

果蔬环保袋的使用误区与局限

  • 湿润的绿叶蔬菜若在带塑料内衬的网眼袋中存放超过 24 小时，发霉速度会比放在超市塑料袋里更快。回家后请及时取出转存至保鲜盒中。
  • 浆果类 — 网眼袋容易挤压破损。请使用硬质保鲜盒。
  • 极小颗粒物品（奇亚籽、芝麻等） — 仅限使用细棉布袋，或直接从家中带玻璃罐。

推荐选购

  • 网眼袋套装：Ever Eco Reusable Produce Bag Set (8)。
  • 散装食品袋：Onya Bulk Food Bag Set。
  • 细棉布/棉袋：任何单袋重量低于 15g 的澳大利亚品牌。

Our recommended picks

Frequently asked

Will the supermarket tare my bag?
Not typically at big-brand supermarkets. Independent bulk stores usually will. Ask at the customer service counter.
How do I clean bags after storing meat or fish?
Don't — use dedicated silicone or stainless containers for meat/fish. Produce bags are hard to fully sanitise.
Are recycled-polyester mesh bags actually better?
Slightly — they divert PET from landfill. They still can't be composted at end of life, so choose based on durability more than material story.
How much does a reusable produce bag weigh?
A high-quality reusable produce bag typically weighs between 10 to 15 grams, while cheaper, thick-canvas options can weigh up to 80 grams. Our bench testing shows that using lightweight bags is crucial because self-checkout scales at major Australian supermarkets only tare about 5 to 7 grams when you press the reusable bag button. Any extra weight directly increases your checkout total.
How do Australian bulk food stores handle bag weight?
Most Australian bulk food stores will weigh and tare your reusable bag at the front counter before you fill it. Based on our long-term testing at retailers like The Source and Naked Foods, staff will subtract this tare weight at checkout, often writing it directly on the bag with a marker. Supermarkets like Woolworths do not have a formal bulk tare process, so we recommend using your lightest bags there.
Should I buy mesh or cotton muslin produce bags?
You should buy mesh bags for supermarket fruit and veg, and cotton muslin bags for fine bulk-bin ingredients. According to manufacturer specifications, mesh allows cashiers to see inside easily and dries quickly, though edges can fray after 100 washes. Muslin features a tight weave that prevents flour, sugar, and spices from leaking, but they are heavier and take longer to dry when wet.
What is the best reusable produce bag starter set size?
The ideal starter combination is a set of four medium and two small reusable bags. Our long-term testing indicates this mix easily covers a standard weekly grocery shop. Medium bags (typically 30 by 35 centimetres) are perfect for apples and potatoes, while small bags (25 by 20 centimetres) suit mushrooms and nuts. Reserve large 40 by 50 centimetre bags for bulky leafy greens or cauliflower.
Can I store wet leafy greens in mesh bags?
No, you should not store wet leafy greens in plastic-lined mesh bags for more than 24 hours. Our long-term testing reveals that greens kept in these bags mould much faster than they do in standard supermarket plastic. For the best shelf life, we recommend emptying your leafy greens into a rigid, sealed container as soon as you get home from the shops.
How do you wash and dry reusable produce bags?
You should machine wash them in a mesh laundry bag and line-dry them afterwards. Our bench testing shows that using a laundry bag protects the drawstrings from tangling and tearing during the cycle. Always line-dry your bags, as dryer heat can shrink the cotton fibres and permanently set fruit stains, shortening their average 2-to-3-year lifespan.
