When it comes to packaging, one size certainly doesn’t fit all. Choosing the right sack for your business can influence everything from production efficiency to shelf appeal and brand perception. Whether you’re in food, feed, construction, or chemicals, understanding the different paper sack options available and how easily you can switch, can make a measurable difference to your operations.
At Peter Marsh Group, with nearly two centuries of UK manufacturing expertise, we produce a wide range of bespoke paper sacks to suit every sector, product type, and brand requirement.
Block Bottom Sacks – Strong, Stable and Retail-Ready
Best for: Food products, flour, sugar, pet food, and chemicals
Features & Benefits:
Block bottom sacks (also known as square bottom sacks) are designed to stand upright, providing excellent stability on shelves and pallets. Their shape ensures easier stacking and efficient storage, while their smooth surfaces make them ideal for high-quality printing and perfect for brands that want their logo and design front and centre.
Why switch: If your current sacks collapse or create inefficient pallet loads, upgrading to block bottom sacks can improve handling, enhance product presentation and reduce waste in transit.
Roll Bottom Sacks – Durable and Cost-Effective
Best for: Animal feed, flour, powders, seeds, minerals, or bulk materials
Features & Benefits:
Roll bottom sacks are constructed for strength and durability, providing extra protection for heavy or coarse products. Their rolled and glued base makes them highly resistant to splitting or tearing under load and include an easy open variate suitable for food products.
Why switch: For businesses dealing with heavier contents, roll bottom sacks can reduce product loss from damaged packaging. Delivering long-term savings and improved reliability.
Stitched Bottom Sacks – Traditional Strength for Heavy-Duty Applications
Best for: Root crops, potatoes, construction materials such as cement, aggregates and powdered chemicals
Features & Benefits:
Stitched bottom sacks offer exceptional mechanical strength, secured with thread stitching to withstand rough handling and moisture exposure. They are often used where products face demanding transport conditions or where additional robustness is required.
Why switch: If you’re currently importing heavy-duty sacks or dealing with damaged shipments, switching to locally produced stitched sacks provides reliability, shorter lead times, and the reassurance of UK-based quality control.
Valve Sacks – Fast Filling and Cleaner Operations
Best for: Chemivals, cement producers, sugar and powdered products
Features & Benefits:
Valve sacks include a valve opening for quick, dust-free filling on automated lines. Once filled, internal pressure seals the valve naturally, removing the need for separate stitching or gluing. This design improves filling efficiency and hygiene control. Especially vital in food production.
Why switch: Businesses moving to valve sacks often see reduced spillage, faster filling times and a more controlled packaging environment. It’s an ideal option for modern, high-volume production lines.
