Businesses have a lot to lose by choosing the wrong packaging supplier, especially when it comes to bulk bags.

Questions to ask before choosing a bulk bag supplier

  1. What types of bulk bag do you supply? – This will give you an indication of their portfolio and ability to meet your requirements. Be sure to ask about specific properties of the bags, such as anti-static protection, UV coatings, waterproof linings and breathable fabric.
  1. Where do you source your materials? – Some suppliers, like Custom Bulk Bags, manufacture their products in-house and others import the raw materials. If there is any issue with a bag, then a manufacturer can take responsibility. However, if the company imports materials, then the onus of responsibility can be more complicated.

  1. How many bags do you have in stock? – Some suppliers keep large stocks on hand so that any increase in demand can be met quickly. Other suppliers prefer to manufacture as orders come in, which makes them less able to meet supply demands in a short period of time.
  1. Do you offer design and customisation? – Most companies like to have their logos and product information printed on the exterior fabric of their bulk bags. Custom Bulk Bags offers custom printing and design of packaging, which includes logos, barcodes, origination stamps and product information.
  1. How does the ordering process work? – Each supplier will have its own method for taking orders and ensuring that the correct specs are included on the bags. This explanation will give you an understanding of the process and what to expect from your supplier. Also, check if there is a minimum order quantity or requirement.
  1. How long is the lead time on an order? – Always find out how long you’re expected to wait for your order. As mentioned, some suppliers keep a stock of products that will allow them to fulfil the order quickly. However, if you’re buying highly-customised bulk bags, then you can expect lead times to be a bit longer.

  1. Who will be my main point of contact? – Be sure to establish an individual at the supply company who you can reach out to for any queries and updates. If there are additional specs or if you have any billing concerns, you need to know who to speak to.
  1. Do you offer any discounts? – Some suppliers may provide discounts for large orders or on stock that has not moved. This could be your chance to score high-quality bulk bags at a reduced price.
  1. What quality control measures are in place? – Most reputable suppliers will hold international certification for quality assurance, such as ISO 9001. These accreditations are a guarantee of standards and quality. Find out about testing processes, such as topple tests, as an indication of durability and safety.
  1. Do you have any customer references or testimonials? – A trustworthy bulk bag supplier will be able to tell you which other companies make use of their products. In some cases, they can show you written proof of satisfaction from clients.
  1. Are there any terms and conditions? – Always read and understand the fine print. Some suppliers offer warranties, return policies, waivers and more. Ts & Cs can be helpful, so be sure to ask about the minor details of any agreement before signing.
