WH Global Pack blog

If you are considering starting a new business, you will need poly mailers to ship your products. Or you can also start a business supplying poly mailers to various companies. Whether you start a business of poly mailers or not, you still have to source them to pack and ship your products.

Many new entrepreneurs find themselves hitting the wall when they try to find a good quality poly mailer for their products. Good-quality mailers are not easy to find, no matter how much you research poly mailers. In this article, I will tell you how to find a reliable poly mailer manufacturer.

What is a poly mailer?

Poly mailers plastic bags are created to carry and ship various products. Because of their lightweight and sturdy nature, poly mailers are widely used worldwide. Poly mailers also have a self-sealing fold-over lip, so there is no need for tape. The best thing about poly mailers is that they are thin but durable, which is why they don’t take a lot of space in a truck while in transit.

Domestic or overseas manufacturers

There are two types of suppliers in the market. Before stepping into the market, you should know the basics about them.

Domestic supplier

If you are trying to source poly mailers for your business, you have two options; you can opt for domestic or overseas suppliers. However, securing two manufacturers, one domestic and one overseas, is better. Your domestic manufacturer will be a backup supplier if your overseas shipment is delayed.

But before you choose a local manufacturer, take a look at its pros and cons.


  • High-quality manufacturing of poly mailers.
  • Better labor standards.
  • Ease of communication and no language barrier with the manufacturer.
  • Marketing appeal.
  • You can verify the manufacturer’s reputation easily.
  • Faster shipping.
  • Payment security.


  • Expensive products.
  • Limited number of manufacturers to choose from.

Overseas supplier

If you are looking for an overseas supplier, then look at Asian countries like China, India, and Taiwan. These countries can provide poly mailers at a cheaper cost because of low labor costs. However, you should look at their pros and cons before making a final decision.


  • Cheaper products because of low manufacturing costs.
  • Ling list of manufacturers to choose from
  • Services like Alibaba make navigation of suppliers easy.


  • The risk of encountering low-quality products is high.
  • Usually low labor and manufacturing standards.
  • There is often a language barrier with the manufacturer making communication difficult.
  • Verification of the manufacturer is difficult.
  • Long shipping time.
  • Custom clearance and product importation.
  • Less payment security.

How to find a reliable poly mailer manufacturer?

Finding a manufacturer who can supply premium quality poly mailers to you can be tricky. Even after thorough research, the risk of encountering a lousy supplier is pretty high. That is why I recommend WHpack, a trustworthy and reliable supplier. They can supply customized premium quality poly mailers to you.

To find a reliable poly mailer manufacturer, you have to undergo the following steps.

  1. Research
  2. Collect information
  3. Communicate your designs with the manufacturer
  4. Order samples
  5. Negotiate payment or other necessary things.
  6. Place your order


The first step you have to take in order to find a reliable poly mailer manufacturer is to research online and get a list of some trustworthy manufacturers. Here are some platforms where you can find a reliable poly mailer manufacturer.

  1. Alibaba

China has become the biggest market for everything. And at Alibaba, you can find and connect with all manufacturers from China. Mainly, you can find existing poly mailers on Alibaba. However, you can contact manufacturers to ask for customized poly mailers for your brand. You just have to search poly mailers in the search bar and get the list of products. Browse through the list, check reviews, and select the best manufacturer for you.

Alibaba is a safe place to buy poly mailers. But while finding manufacturers on Alibaba, keep in mind the following things:

  • A gold supplier pays a membership fee to Alibaba. That’s why it does not always guarantee a good quality product.
  • A verified supplier is someone whose manufacturing facility is verified by Alibaba or third-party evaluation service.
  • Look for trade assurance, which means a free service will protect your order from payment to shipment.
  • Ensure that the person you are ordering from is not a trading company. The trading company is just a middleman and, therefore, will be unable to manufacture your customized poly mailers.
  • Directories

Online free supplier directories are another place to research manufacturers. These directories have manufacturer’s catalogs, including profiles of thousands of manufacturers, suppliers, and wholesalers. Below I have given the list of famous domestic and overseas directories. You can visit these directories and research poly mailer manufacturers.

Online domestic directories
  1. ThomasNet
  2. Maker’s Row
  3. MFG
  4. Kompass
Online overseas directories
  1. AliExpress
  2. Indiamart
  3. Sourcify
  4. Google

Google has become the most widely used platform in recent years. It is easy to search and find anything on Google. Moreover, Google gives us our desired results in only the first few searches. You can also find poly mailer manufacturers and suppliers on Google.

However, many manufacturers haven’t updated their websites, and that’s why they fall behind Google’s algorithm changes. So it would be better if you also look at the second page of Google. You can also try searching using alternate words like replacing ‘manufacturer’ with ‘supplier or wholesaler. Alternating the search words can help you get better results.

  • Referrals

You can get the best leads on poly Mailer manufacturers through your referrals. If you have an excellent professional network, don’t hesitate to ask them for referrals. Your professional network may know someone trustworthy.

You can also use social media to get referrals. Facebook groups and online communities of e-commerce business owners make life much easier than before. Moreover, if you find a supplier that doesn’t seem right for you, you can ask him to tell you about other poly mailer manufacturers and suppliers.

  • NAICS codes

NAICS stands for North American Industry Classification System. You can search poly mailers by their NAICS code and get a list of suppliers. Every single poly mailer manufacturer will be available at the NAICS. You can easily find local or domestic poly mailer manufacturers by visiting the NAICS directory.

Collect information

Now you have a list of potential manufacturers; you should thoroughly collect information about them. Check their reviews to look for any red flags. Aside from getting information on the reputation of the manufacturer, gather details on the following things:

  • How much will the poly mailers cost?
  • Can the manufacturer provide customized poly mailers?
  • Does the manufacturer have the equipment and skill to produce high-quality poly mailers?
  • How much time will they take to ship your order? 
  • What is the shipping cost?
  • What is the minimum order quantity?
  • What is the cost per unit?
  • What is the deficit policy of the manufacturer?
  • What are the factory conditions, and is the manufacturer ethical and sustainable?
  • Discuss payment options and terms with the manufacturer.

Communicate your designs with the manufacturer

Communication is a vital component of a successful business relationship. So don’t be shy to communicate with your manufacturer. You can use Skype call, email, or WeChat to communicate with your supplier.

Ask your manufacturer about the design machinery available at their factory. Ask if they can deliver a customized poly mailer with your brand logo on it. You can communicate your design via sketches, instructions, or reference photos. You can also look for a freelancer to do customization of your poly mailer if your manufacturer can’t do it.

Order samples

Before placing the complete order, you should ask your manufacturer for the samples. Inspect the samples for quality, size, material, and all other necessary things. Once you are happy with the quality, place the full order.


Negotiation is an essential part of every successful business. Before placing the order, you should negotiate payment terms and MOQ. Negotiate in a manner so that both parties can get profits and become happy.

Place your order

Once you are 100% satisfied with the quality of poly mailers and MOQ and payment terms suit your business, then place your order. Once you place the order, your manufacturer will start the production process immediately.


Finding a reliable poly mailer manufacturer is indeed a frustrating task. Trying to find a manufacturer that can be a good fit for your business requires patience and perseverance. WHpack is a well-known name for manufacturing and supplying poly mailers. You can also check them out.
