Paper Sacks: UK Manufacturer
From human food to animal feed, fine powders to cement, we have the paper sack you need, whatever your contents. Read our guide then talk to our team.
Open Mouth Block Bottom Paper Sacks
An open mouth block bottom paper sack is mainly used by food companies and animal feed producers. You can have it printed on both sides and on the block bottom base.
Like all paper sacks, it’s formed with piles of paper coming together (usually three) which gives it its strength, then the block base is formed and glued in place.
You can choose from:
- Tubed in or loose polythene liners
- 2 – 4 ply
- Natural or bleached Kraft paper
- 6 colours
- Automatic palletisation
Specific or speedy, we can help
We can supply your bags in the exact shape, size and design you need. And if you want something fast, we can do that too. All of our unprinted stock bags are ready to go, whenever you want.
Our team typically stores thousands of different SKU numbers under ”Bulk Bags”, but we can customise the bulk bags, including paper sacks, to meet your unique requirements.
Each paper sack has different strength and resistance properties, but we can tailor specifications to your requirements: through thicker paper, additional ply or adding a liner.
Sewn Bottom Paper Sacks
The staple bag for the milling, animal feed and potato industries. These open-mouth sacks are formed by piles of paper coming together and are then stitched at the base with a crepe paper to form a seal.
You can choose from
- Plain.
- Bespoke print in up to 6 colours.
- Pillow or gusseted design.
- Plastic or paper handles.
💡 Our paper sacks have BRC food safety accreditation.
Rolled Bottom & Rolled Top Paper Sacks
A more ‘up-market’ version of the sewn bottom sack. These sacks are really designed with the end user in mind as they’re predominantly for animal feed.
The paper plies are formed to create the sack size and then top is rolled and glued to form a seal. When you’re ready to use, you simply break the seal by hand.
Technically manufactured upside down (it seems that way because the print’s upside down until you fill the bag) they’re filled from the bottom up. The outer ply of these sacks is usually a clay coated finish or gloss – giving them a more appealing look.
It’s all about the valve…
Key to every sack is the valve. With any sack that you go for, once it’s filled it becomes a cube – and it’s down to the valve to stop your product escaping. So the valve can be made in several different ways, depending on what’s inside.
That’s also why it’s important that you fill these sacks to their maximum, so the weight of your product acts as a method of closure itself.
What all of this means is that there’s no set size for these bags – we’ll make them to suit the way that you fill, what you’re putting inside, the characteristics and density.
In terms of valve and machine compatibility, our products are ideal for high-speed packaging of dry, granular, or powdered products in industries like building materials, chemicals, food, and agriculture.
Paper Valve Sacks
Invented in 1898, paper valve sacks have been doing a great job as packaging for well over a century. Mainly used for fine powders, foodstuffs and cement markets, they have a valve in one corner that can be either internal or external.
Made from multiple plies of paper tubed together to give the sack its strength, you can also opt for an inner polythene ply to stop water getting inside.
➡️ The recommended maximum fill weight and stacking height is on a case-by-case basis, depending on the size and strength of each stack, as they can be stacked on top of each other on a pallet for shipping/transport.
