500g 100x340mm Valve Kraft Paper Side Gusset Pouch/Bag (100 per pack)

This bag is designed to hold approximately 500g of coffee beans. Other products may occupy more or less space depending on their density, shape and particle size. We recommend testing a sample with your own product before ordering in volume.

For guidance on bag size, see our size chart, which suggests suitable bag sizes using examples including pick-and-mix sweets, protein powder and sugar or salt. This provides a useful starting point for comparing products with different densities and forms.

The bag measures 100mm(W) x 340mm(H) + 60mm(G), Width x Height + Total Bottom Gusset.

Freshly roasted coffee releases carbon dioxide. The one-way valve lets that gas escape from the bag but does not let outside air back in, so the bag does not balloon or put pressure on its seals.

If you are packing whole coffee beans, especially freshly roasted, a degassing valve is strongly recommended. Without one, the gas builds up, the bag balloons, and it can eventually burst or force a seal open. For products that do not release gas, such as tea, granola or confectionery, a valve is not needed — view our Side Gusset Bag.

No. A label, sticker or stamp over the valve stops it releasing gas. Please position labels clear of the valve.

The valve lets gas out and restricts air getting in, which supports your coffee as it degasses. It does not make the bag airtight or guarantee a particular shelf life. Freshness also depends on your roast, packing process, storage and how the bag is resealed after opening, so please validate this with your own coffee.

That is down to your roast and your own practice. Roast level, bean type and resting time all affect how much gas is released. Please test a filled, sealed sample over several days to confirm the bag does not inflate.

The bag is designed to be heat sealed initially, and if contents are left within the bag, it can be folded and secured after opening with a peg, clip or tin tie.

Yes. The bag is opaque, keeping the contents concealed and protected from light.

No, this bag is not recyclable. It is constructed from multiple layers which cannot be separated for conventional recycling. If you need a recyclable alternative, please view our Recyclable Pouches stand up pouches.

No. It is neither compostable nor biodegradable. Please do not describe or label it as compostable, biodegradable or home compostable.

Kraft paper is an uncoated natural material, so it can mark, scuff or stain more readily than a film surface, and it should be kept dry. Handle and store the bags/pouches in dry conditions and avoid chilled, frozen or humid environments unless you have validated this with your own product.

Kraft paper is a natural material, so shade and texture can vary slightly between production batches. If an exact colour match matters to you, please order a sample and speak to us before ordering in volume.

The bag is designed to be heat sealed. Seal settings and results depend on your equipment, product, temperature, dwell time, pressure and production conditions. Please test the bag with your product before commercial use.

Food-contact suitability must be confirmed for the exact bag construction and your intended application. Please request the relevant technical specification and, where applicable, food-contact documentation before ordering or using the bag.

No general hot-fill or liquid-product claim is made for this bag. Please contact Rightpak before using it with hot, warm, wet, liquid, acidic, oily or other specialist products.

Products are sold in multiples of 100 bags and may be supplied in more than one inner bag or carton for safe handling and delivery.

Yes. The minimum order quantity for ready-made stock bags/pouches is 100 bags/pouches, excluding fully customised bags/pouches.

Stock bags/pouches are sold in multiples of 100, so you can order 100, 200, 300, 400 bags/pouches and above. Fully customised bags/pouches are subject to separate minimum order quantities.

Bulk-buy discounts apply when you order larger quantities of the same product and SKU. Different products, sizes, colours or formats cannot be combined to qualify for a quantity discount.

Yes, and kraft is one of the best bag materials for it. The uncoated paper surface accepts ink from a rubber or polymer stamp, so you can stamp your logo, business name, batch number, roast date or flavour directly onto the bag. It gives an authentic, handmade finish and avoids a minimum print run on labels, which makes it well suited to small batches and market stalls.

Results depend on your ink, stamp and how much ink you apply. Please order a sample and test first. Ink on uncoated kraft can take time to dry and may smudge or transfer if handled too soon, so stamp before filling where possible and allow the ink to dry fully. We cannot guarantee stamping results, as the ink and method are yours.

Ink choice and food-contact compliance are your responsibility. Rightpak's documentation covers the bag as supplied and does not extend to stamped or altered bags/pouches.

Yes. Kraft paper takes labels well and the natural surface suits both paper and printed labels. Because kraft is a textured, uncoated material, we recommend testing your label on a sample to check adhesion and finished appearance before ordering in volume.

We would advise against it, and we do not offer it. Applying ink and heat to a finished bag can affect the inner food-contact layer and risks migration, so the bag may no longer be suitable for food use. Once a bag has been over-printed after manufacture, it can no longer be relied upon as suitable for food contact, and our technical and food-contact documentation no longer applies to it.

Custom printed bags/pouches work differently. The design is printed as part of the manufacturing process, before the bag/pouch is laminated and formed, so the print is sealed within the structure, and the food-contact layer is unaffected.

Stock bags/pouches are ready-made, held in stock and supplied unprinted, so you add your own labels. Minimum order quantity is 100 bags/pouches.

Custom printed bags/pouches are manufactured to order with your design printed into the bag/pouch during production, rather than applied afterwards. You choose the size, material, finish and features, and the print covers the full bag. Minimum order quantities and lead times apply, and we will guide you through artwork requirements.

If you would like your branding on a stock bag/pouch in the meantime, labels are the right route, and many of our customers start there before moving to custom printed bags/pouches as volumes grow.

Relevant documents may be available for approved business customers. Request access before ordering or using the bag where your application requires food-contact, technical, regulatory or quality approval.
