Poly mailers, also known as polyethylene envelopes, are lightweight, durable plastic packaging bags. Made from a synthetic material of polyethylene, Poly mailers are able to protect the product inside from weather conditions such as rain or high humidity, and can be printed on poly mailers. Poly mailers offer strong protection against dust, moisture, dirt and tampering, ensuring your items reach your customers intact. Additionally, they are cost-effective, easy to store, and can be customized to enhance branding.
With competitive price and timely delivery, Mingyi sincerely hope to be your supplier and partner.
These are basic standard polyester mailing bags, usually white or gray, without any padding or lining. They provide lightweight protection for items that don't require additional cushioning, such as clothing, magazines, or books. Flat-lay mail is generally less expensive and can be self-sealed with tape. Suitable for items that are durable or already protected and do not require additional cushioning.
The mailers are made from plant materials such as cornstarch or other biodegradable polymers that break down into compost under proper industrial composting conditions. Similar to a standard lay-flat mailer, but made from compostable materials that break down and return to nature.
The mailers have a clear plastic front so the contents can be seen, while the back is opaque to allow for labeling. They are ideal for shipping printed materials such as catalogs or brochures. Products can be displayed as they arrive at the customer's doorstep. Shipping information, labels and branding can be added to the back of the mailer.
They feature expandable side gussets to accommodate larger items. High-strength seams keep product secure even when overstuffed.
They feature bubble wrap cushioning lining to provide extra protection for fragile items like jewelry, electronics, or delicate books. The bubble lining adds some bulk but protects against impact.
Tyvek Mailing Bags are made from polyethylene fiber, making them extremely durable and tear-resistant, making them more durable than other types of polyethylene mailing bags and ideal for transporting important documents or photos.
Similar to flat mailers, but available in a variety of colors, they build branding and make your packaging stand out.
They have two adhesive strips - one for initial shipment and one for customers to easily return the product.
Slim mailers are designed for shipping long, narrow products such as posters, wallpaper rolls, or fabrics.
The type of plastic mailer chosen depends on the products being shipped, the level of protection required, and branding requirements.
Made from pre-consumer or post-industrial recycled plastic waste rather than virgin plastic. They help reduce the production of new plastic while giving existing plastic a second life. Recycled plastic mailing bags are durable, lightweight, and customizable, making them an excellent choice for environmentally conscious brands.
Heavy-duty, tamper-resistant polyethylene mailer ideal for larger items.
Similar to compostable mail, but made from plastic, it will break down through natural processes over time, even if not industrially composted. Polyethylene-free, often made from ethanol from plant-based sources like cornstarch and sugar cane, is another sustainable packaging option for eco-friendly brands.
Polyethylene mailers are generally much less expensive than boxes or other packaging options, typically costing about $0.25 per mailer when purchased in bulk. Light weight and low profile help reduce shipping costs, especially when rates are determined by weight or dimensional weight.
Poly mailers take up very little space compared to boxes, making them more efficient to store and ship. They don't require any assembly and stack neatly.
Polyethylene mailers feature self-sealing fold-over lips, eliminating the need for tape or additional packaging. Shipping labels can be affixed directly to the mail. Can be customized with branding for a professional look.
Polyethylene mailers provide a waterproof and dustproof barrier to protect contents during shipping.
They are tear-resistant and can withstand the impact typical of non-fragile items during transportation.
Bubble mailers provide extra cushioning for slightly denser items like books or CDs.
Many plastic mailing bags are reusable, recyclable, or made from biodegradable materials, reducing their impact on the environment.
Polyethylene mailers offer little protection for fragile or breakable items such as glass, ceramics, or electronics. Standard poly mailers without bubble lining do not cushion products from impacts or drops during shipping.
Polyethylene mailing bags are designed to ship one or several soft goods at a time. They are not suitable for transporting multiple items together, especially if the items are rigid or need to be separated.
The adhesive tape on polyethylene mailers may not always seal properly, which may cause the contents to spill if the mailer tears during handling. Polyethylene mailers offer little tamper resistance compared to sealed boxes.
Polyethylene mailing bags are made from plastic, which is not biodegradable and takes hundreds of years to break down in landfills. As sustainability becomes increasingly important to consumers, using plastic mailers that are not eco-friendly can harm your brand’s reputation.
Polyethylene mailing bags have a limited range of sizes and therefore cannot accommodate very large, bulky or irregularly shaped items.

Lightweight
Plastic stands at number one when it comes to lightweight packaging material. As per a study, alternative materials, such as paper, glass, aluminum, paperboard, and rubber are 4.5 times heavier than plastic on average. The alternative packaging materials require substantially more material to create the same packaging as plastic.
Plastic packaging is both strong and lightweight. With this winning combination, plastic packaging protects the product and keeps them safe and secure. In fact, it also saves you from manufacturing as well as shipping costs. Also, as plastic is light in weight, it leads to its superior sustainability.
Inexpensive
Plastic packaging is very cost-effective. The manufacturing cost of plastic is less than other materials.
First, it is inexpensive, and second, due to its lightweight, it helps save on shipping and transportation costs as well. So, it saves both in the cost of acquiring it and the cost of getting the products to the consumers. Its material resource efficiency also helps save money.
Versatility
Plastic is extremely versatile, and it can be molded into any shape. Think of vast plastic packaging variety and you will see plastic films, bags, pouches, sleeves, trays, bottles, drums, shells, and pots.
It is difficult to think of a material that is more versatile than plastic. The following are a few things plastic can do:
Sustainable
Though many think that plastic is dangerous for the environment, the reality is the opposite. Many of the qualities of plastic are environmentally negative, such as its resistance to corrosion. But these qualities make plastic very resource-efficient. Plastic packaging can be recycled frequently.
Other Benefits
Plastic helps in every other aspect of life. It helps in storing food and water. Apart from being cost-efficient and durable, plastic packaging is heat and water-resistant as well. Some plastics are recyclable as well which makes them more efficient than paper alternatives like paper bags.
Cons of Plastic Packaging
Plastic is non-biodegradable in nature and because of it, it has become one of the harmful substances. The following are the cons of plastic packaging:
Non-renewable Nature
Plastic packaging is made of non-renewable resources. This feature makes it less desirable than other alternatives. Plastic takes millions of years to degrade. It only contributes to landfills and disturbs the ecosystem.
Burning of Plastics is Harmful
Burning plastic to get rid of it is not the right solution. When you burn it, it releases a lot of toxic chemicals that can impair the lives of plants and animals. So, it is harmful to the environment.
Environmental Pollution
A large number of plastic bags are thrown each year. This garbage ends up in the ocean polluting it and disturbing the marine life and ecosystem. Also, sometimes the presence of microplastics in the food plastic packaging ends up on the food which may contain harmful compounds.
Common Types of Plastic Packaging
As said above, plastic is a very effective packaging material and is used widely all across the globe. The following are a few common types of plastics used in plastic packaging:
LDPE - Low-Density Polyethylene
LDPE is yet another commonly used plastic that is tough but flexible. It is an excellent barrier to water, oxygen, and carbon dioxide. FDPE is an ideal option for food packaging. It is considered a safe plastic option and products made of LDPE can be recycled into bin liners, paneling, floor tiles, shopping bags, and shipping envelopes. Some common uses of FDPE include bubble wrap, zip lock bags, stretch film rolls, playground equipment, and grocery bags.
HDPE – High-Density Polyethylene
HDPE is a common type of plastic generally known for its strength ratio and versatility. It is resistant to chemicals as well. Its common uses include bottle caps, cosmetics, and bottled liquids like detergent, shampoo, and milk. HDPE plastic is a safe plastic and can be recycled into rubbish bins, pens, fencing, outdoor furniture, and detergent bottles.
Polystyrene
Polystyrene or Styrofoam is produced in a foam or rigid form. When in foamed form, it is the best option for transporting either cold or hot food and drinks. The common uses of polystyrene include disposable razors, meat trays, CD cases, and protective packaging. Styrofoam has a very bad reputation for a recyclable material as it is hard to recycle. However, it still can be recycled into foam packing, insulation, vents, and flowerpots.
Polypropylene
Polypropylene is a flexible but strong plastic that can be molded into a wide range of functions to suit your needs. This type of plastic can hold heated contents and it is resistant to chemicals and melting points. Polypropylene can be recycled into battery cases, bins, brooms, pallets, bicycle racks, and signal lights. Some of its common uses include plastic cutlery, containers, medicine bottles, PP strapping, and medical instruments.
