d.a.pak specialises in bulk bags that are expertly designed to handle sand with ease. With our full range of options and sizes, you’ll find the perfect bag for your specific sand application, whether it’s sharp sand or builders’ sand.
We know that your sand-related business has unique needs. That’s why our FIBC bulk bags can be customised and tailored to your specific needs and branding, making them a perfect fit for your operations.
Bulk bags can be certified to carry contents weighing anything from 50kg up to 2000kg. The heavier your product is, the heavier the grade of fabric needed to manufacture the bag so it conforms to the safe working load. A bulk bag can carry up to 1000 times its own weight.
Bulk bags are predominantly made from polypropylene (PP), a high-strength thermoplastic that’s very strong yet flexible.
The polypropylene is extruded in tubular form and then sliced into threads and woven together (warp and weft) to form a very strong, durable fabric.
The most basic form for filling a bulk bag is using a fully open top which is ideal for products like sand and aggregate, where the product can flow easily into the bag and it does not need to be protected from the elements.
Bulk bags can have a filling spout which can be attached and tied to a machine or hopper feeder pipe, this allows the product to be filled directly into the bag and tied off once complete.
Skirt or duffle tops are an ideal way to fill bulk bags from a free flowing conveyor feed. The bag is effectively fully open on the top allowing maximum opportunity for materials to free fall and fill the bag.
Plain base with no method for discharge.
The most common way to empty a bulk bag is through a discharge spout. These spouts are folded (swan necked) and tied so they effectively form a flat base when not in use however when emptying the contents of the bag the spout can be untied and extended to allow the product to flow safely out of the bag. By adjusting the tie on the spout you can determine the radius of the discharge spout which will allow you to effectively control the flow rate of product being discharged.
Bulk bags can be designed with a full base discharge with four panels of material sewn into each side of the bag that cross over to form a flat base within the bag. The bag will also have an outer flap that can be securely tied. When untying the base outer flap, the four inner overlapped panels release to form a full base discharge.
Sharp sand, prized for its coarser texture and angular grains, is commonly used in construction, landscaping, and drainage projects. d.a.pak‘s bulk bags for sharp sand are designed to withstand the abrasive nature of this material, providing secure containment and hassle-free transportation to ensure your projects stay on schedule and within budget.
Builders sand, essential for creating mortar and concrete mixes, requires reliable packaging solutions to maintain its quality and consistency. d.a.pak‘s bulk bags for builders’ sand are engineered to handle the weight and flowability of this material, offering sturdy construction and easy handling for efficient construction operations.
Silica sand, known for its high purity and versatility, finds applications in various industries, including glassmaking, foundries, and water filtration. d.a.pak’s bulk bags for silica sand are meticulously crafted to preserve its purity and prevent contamination, providing safe and efficient packaging solutions that meet the stringent requirements of your industry
Most bulk bags and FIBCs are produced from type A fabric, a standard woven polypropylene fabric that won’t give you static protection. You shouldn’t use this bag where there’s an air dust mixture, explosive gas or flammable solvent atmosphere.
Type B bulk bags are also produced from non-conductive woven polypropylene fabric and have a breakdown voltage of maximum 6kV.Like type A bulk bags, you can’t use them as anti-static bulk bags as they can’t remove electro charge. As the fabrics used in type B bulk bags have a low breakdown voltage, they will prevent propagating brush discharges which can ignite an air dust mixture – but explosive gas atmospheres could still be ignited. You can use type B bags to safely store and transport dry flammable powders.
Also produced from a non-conductive woven polypropylene fabric, but with interwoven conductive threads that form a connected grid. The grid is a maximum of 50mm mesh size with a maximum distance between each other of 200mm (if the threads only go in one direction). These conductive threads are grounded whenever your bulk bag is filled and discharged. If they’re grounded correctly, there’s no risk of incendive discharges. You can use Type C bulk bags in environments where there’s an air dust mixture, as well as in explosive gas atmospheres.
Type D bulk bags and FIBCs are made from non-conductive woven polypropylene fabric with conductive fibres that aren’t connected to each other.
So this type of bulk bag isn’t conductive, but instead dissipates charge into the environment through corona discharge.
You have the option of treating these bags with an antistatic coating that reduces the surface resistance of the fabric. Because the electro-charge is dissipated through corona discharge, this type of bulk bag can charge conductive objects and people nearby, which could then cause electrostatic sparks on contact with grounded objects, possibly igniting air dust mixtures, explosive or flammable gas atmospheres nearby.
So it’s vital that whenever you’re filling or discharging a Type D bulk bag or FIBC in a hazardous area, all conductive objects or people nearby are grounded throughout. You’ll find full Instructions for grounding on the label of your Type D bulk bag.

Bulk bags can be manufactured to endless designs and specifications, depending on how you need your products to be filled, stored, transported and discharged. So it’s well worth thinking about:
Here’s our practical guide to the different bags we offer and how they’re constructed, plus some extra info to help you decide on the best one for you.
The name ‘bulk bag’ covers any kind of FIBC or flexible intermediate bulk container. They’re an ideal way for you to transport and store dry, free flowing materials safely, securely and cost effectively.
Yes! – Bulk bags can be made in a variety of different colours.
Yes you can! Bulk bags are made from Woven Polypropylene which is recyclable. Your bulk bags will need to be empty & baled for collection from a recognised Bulk Bag recycling centre to come and collect for you.
We carry a large range of stock items which are ready for immediate despatch. However, if you require something a little more bespoke these may need to be ordered in for you.
A bulk bag with a safety factory of 5:1 implies that the bag is only suitable for single trip use. A bag with a safety factor of 6:1 can be used multiple times, making the bag more environmentally friendly.
Our office opening hours are from 8am – 5pm Monday to Friday, excluding Bank Holidays.
Yes! – Bags can be printed to your requirements. Lead time on printed bags is 10-12 weeks with a minimum order of 500 – 1000 bags.

Bulk bags can be made for either single trip or multi-trip use, and you can find out which yours is from the safety label that’s attached to it.
A safety factor of 5:1 tells you that your bulk bag is for single trip use only – so you can only fill it once, but it can be lifted several times on its journey.
A safety factor of 6:1 tells you that your bulk bag is for multi-trip use and can be emptied and refilled several times – so this is your more economical and environmentally-friendly option.
The safety label will also tell you the ‘safe working load’ your bag can carry – for example, 1000kg. And it will tell you the test house, certificate number and certificate date, together with your bag’s manufacture date and batch number. All of this info is given to show that your bag’s been tested to perform to a safe standard, and so you can trace every step of its production.
Bulk bags can be certified to carry contents weighing anything from 50kg up to 2000kg. The heavier your product is, the heavier the grade of fabric needed to manufacture the bag so it conforms to the safe working load. A bulk bag can carry up to 1000 times its own weight.

For the carriage of dangerous goods in Bulk Bags (FIBC’s) and Soft Sided Packaging
Dangerous goods are those which have been classified to have hazardous materials in all or part of them according to international regulations. The various types of materials are then grouped into 9 classes for identification.
The carriage of dangerous and hazardous goods in bulk bags by road, sea and rail carry the risk of accidents, leading to possible spillage or leakage which could create a risk such as fire, explosions, chemical burn or an environmental issue. Regulations are in place to ensure that those who come into contact during the transportation process, or the emergency services in the case of an incident, can quickly identify the materials being transported to provide a suitable response. These regulations are known as ADR or Accord Dangereux Routier (European regulations concerning the international transport of dangerous goods by road).
It is, therefore, a legal requirement that dangerous goods are packaged in containers which are ‘type approved’ or certified to UN standards as suitable for transportation of these materials. UN Certified Packaging is marked clearly to indicate hazardous materials are being transported.
