The team at Universal Plastics can help you decide which type of poly bag is best for your application.
Once you’ve decided on a type of poly bag, you’ll need to measure your product to determine the necessary dimensions. If you’ve chosen a flat bag, you simply need to choose the right dimensions for length by width. Consider the size of each component and the number of components you intend to place in a bag. For volumes with very small products, consider the overall volume of product that should go in each bag, then calculate the dimensions that would accommodate that volume. It’s important to size up to account for imprecision and to allow room between components.
For a gusseted bag, calculate the desired volume in the same way, but treat the bag as a rectangular prism when translating the desired volume to dimensions. While you should still add a bit to your measurements to ensure the bags have adequate room, the depth and shape of gusseted bags make it easier to get a close and accurate fit.
If your calculations reveal a need for a non-standard size, Universal Plastics can still help. As an industry leader in poly bags, we are happy to accommodate custom orders.
Poly bags are used to pack, store, and ship items of all kinds.
Poly bags can also protect, contain, and display non-food items of all types, including clothing, office supplies, home goods, and more.
Custom printed poly bags help brands stand out with colorful prints and logos, as well as nutrition facts or other specifications. At Universal Plastic, we offer custom printing on clear poly bags of all shapes and sizes, making it easy for clients to both attract customer attention and comply with labeling regulations.
Universal Plastic offers an extensive range of standard and custom poly bags, including:
My name is Garth of JNG Handyman, LLC out of Florida. I had an idea for a product, but finding a bag manufacturer in the US or abroad that would work with me was not happening until I contacted Nat. I can't say enough about Nat and this company; responsive, user friendly, quality product, flexible, works with you, and on and on. When Nat and I started the process of working together on my bags, he stated a 3 to 4 week response time. Eight days from dropping my PO, the bags were delivered.....crushed it!! Now it's up to me to get this product out the door; I am hopefully looking forward to a long relationship with Nat and Universal Plastic Bag Manufacturing Co.
Ever stood in the supermarket wondering if you—or the planet—would be better off if you bought milk in a glass bottle rather than a carton or plastic jug? Or whether it should be a plastic, Styrofoam, or cardboard carton for eggs? Or a can or carton for soup? All packaging decisions involve a tradeoff. Here’s what to consider.
“The sad truth is that food packaging today—whether it’s a soda bottle, pizza box, or takeout container—is made with toxic chemicals that are putting the planet and our health at risk,” says Cassie Huang, a consumer health project manager at the Environmental Defense Fund.
“There are over 12,000 food-contact chemicals,” notes Huang. “They might be added to packaging for functionality, like to make a material water- or oil-resistant. Toxic chemicals could also be used earlier in the supply chain, like in cleaning solutions used on manufacturing equipment.”
So even if you could buy a container that’s free of concerning chemicals—which is next to impossible—your food may have already picked up those chemicals from food processing equipment or storage containers or some other source.
The problem: Some of those 12,000 food-contact chemicals are hormone disruptors—that is, they can turn on, turn off, or alter the signals sent by your body’s hormones.
A few key examples of hormone disruptors, all of which can leach into food from packaging:
Bisphenol A (BPA) is used to make polycarbonate, a ubiquitous hard plastic, and is added to some epoxy resins that line metal cans, jar lids, and bottle caps. Bisphenols are also used to coat thermal receipt paper, where it isn’t bound to the paper and can easily migrate to anything—your hand, for instance—that touches it.
BPA has been linked to health issues like behavioral problems and impaired learning in children, early puberty, infertility in women, and lower sperm count in men.
Per- and polyfluoroalkyl substances are a class of more than 4,000 chemicals that are used in cosmetics, nonstick cookware, waterproof clothing, and more. In food packaging, PFAS are often used to make paperboard oil- and water-resistant. They’re also used in some plastic containers and plastic linings along the food supply chain.
“PFAS are forever chemicals, because they persist in the environment,” says Huang.
“When you toss that brown paperboard takeout container, those chemicals have a second life and leach into the environment, contaminating our water and soil.”
PFAS have been linked to some cancers, immune suppression, high cholesterol, thyroid hormone disruption, and high blood pressure during pregnancy.
They make plastics flexible and are widely used in shower curtains, cosmetics, IV tubes, food processing equipment, and food packaging.

Phthalates have been linked to problems like lower IQ in children, lower sperm count in men, and lower success rates in women undergoing in vitro fertilization.
A perfect planet-friendly food package wouldn’t generate greenhouse gases or cause air pollution. It would be made with a minimal amount of water and no hazardous chemicals. To minimize food waste, it would protect its contents from light, air, and pathogens. You could use it over and over, and it could be recycled when you’re done with it.
That package doesn’t exist. Here are the ones that do.

Confused? These tips may help:
“It’s incredibly toxic to make and recycle,” says Lynn Hoffman, co-president of Eureka Recycling in Minneapolis. Buy eggs in cardboard instead. Get your meat and seafood at the counter, not in the prepackaged Styrofoam trays from the refrigerator case. And when you eat out, bring your own container for leftovers.
”My goal is to avoid plastic whenever I can,” says Judith Enck, president of Beyond Plastics, a project at Vermont’s Bennington College that aims to end plastic pollution. That may mean fewer choices or more prep work.
“I just buy a head of lettuce instead of the fancy greens that come in plastic,” says Enck. “And I don’t buy pre-cut fruit in plastic containers.”
Glass requires more energy than other materials to make and transport, but it likely contains the fewest chemicals of concern and is recyclable forever. Reuse those empty jars as many times as you can. When you’re done, recycle them.
“‘Free from X’ claims don’t necessarily mean you’re in the clear,” says Huang. For example, “there are BPA-free cans, but they may contain a replacement chemical that could be just as harmful. That’s why companies need to make sure they’re replacing with safer chemicals.”
Use glass or ceramic in the microwave.
“Don’t heat food in plastic containers, even so-called microwave safe ones,” says Huang. “Chemicals like BPA are more likely to migrate out of the container when heated.”
“It’s nearly impossible to avoid hormone disruptors in food packaging, so choose the package-free option as often as you can,” says Huang.
“For example, drink your coffee at the coffee shop instead of getting a disposable cup.” (Many places will serve you in a mug.) At a restaurant, bring your own reusable containers to take home leftovers. And at the supermarket, buy dry beans (to skip the can) and pick unpackaged produce.
“It shouldn’t be up to consumers to figure out whether or not their food packaging is safe,” says Huang.
“Companies need to clean up their acts, work with their supply chains, and ensure that their customers can trust them to provide safer and more sustainable packaging options.”
And the government should step up and ban harmful chemicals from coming in contact with our food.
