Poly Bag Types: Flat or Gusseted?
You will get efficient and thoughtful service from sontex.
Aside from material, bag type is another important consideration. Poly bags are available in both flat and gusseted designs.

As their name suggests, flat poly bags are made from seamless tubing that allows them to lay completely flat when empty. These bags can accommodate many commercial and consumer packaging applications ranging from food items to manufacturing components.
Gusseted bags are designed to expand, with extra panels giving these bags a rectangular shape when full. Gusseted bags are ideal for packaging bulkier items. They are also useful for packaging smaller components as gusseted bags fit more product than similarly-sized flat bags, making them more efficient to store or ship.
The team at Universal Plastics can help you decide which type of poly bag is best for your application.
What Size Poly Bag Do You Need?
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.
Common Applications
Poly bags are used to pack, store, and ship items of all kinds.
FDA-approved, food-safe poly bags keep foods fresh and prevent moisture or contamination. At the same time, they offer a simple and attractive way to display bakery items, produce, and bulk foods, especially when printed with custom branding elements.
Small poly bags are an excellent, see-through solution for organizing hardware of different sizes or shapes. These packages are especially useful when shipping products with assembly requirements.
Thin, plain bags are a cost-effective option for vendors that sell bulk goods of any kind. Applications range from single-use bags for bulk grocery customers to sturdier bags that contain pounds of animal feed.

many types of poly bags
to choose from, all with unique features and capabilities, it can be challenging to know which option will work best for your application &#; especially when it comes to something as pertinent as safe food storage.
When it comes to poly bags for food storage, there are some specific considerations you need to take into account. Below, we&#;ll outline some key features to look for before purchasing.
Poly Bags for Food Storage: What to Look For
If you&#;re in the food industry, you know that food safety and freshness are top priorities in gaining and retaining loyal customers. Therefore, it&#;s important to find a packaging and storage solution that guarantees those things. Here are four features to look for in poly bags for food storage.
1. Made with Food Grade Plastic
As its name suggests, food grade plastic is any plastic material deemed safe for use with foods. In order to be considered a food grade plastic, a material must meet various safety standards established by the Food and Drug Administration and other regulatory organizations. These standards ensure that the material meets the following three criteria:
Protective &#; prevents moisture or contamination
Durable &#; protects food items during manufacturing, packaging, storage, and transportation process
Chemically safe &#; has no potential for &#;leeching&#;, which is when chemicals seep into the food
These standards also look for less life-threatening, but still important aspects like whether or not a plastic material affects the taste, odor, or color of the food.
2. Food Storage Poly Bags That Are Thin, but Durable
With food storage, you generally need a bag that&#;s flexible, lightweight, moisture-resistant, and transparent so customers can see what&#;s inside. Luckily, various poly bags offer these benefits.
However, depending on the type of food, size of food, shape of food, and/or quantity of food you&#;re hoping to store, you may need to invest in something a little more heavy-duty. This is where the difference between HDPE and LDPE poly bags come in.
are denser, causing them to be more durable and resistant to tears &#; but they can be less flexible and transparent than other options. Therefore, they&#;re most ideal for heavy, sharp, or bulk food items.
are less dense, causing them to be flexible, transparent, and easy to open. They&#;re the best option for lightweight, low-quantity food items.
3. Able to Withstand Extreme Temperatures
Maybe you need to freeze your food, or maybe you&#;re planning to sell your food at an outdoor market in the summer. Either way, you need to make sure that the type of poly bag you choose can withstand the extreme temperatures you may store it in.
These temperature-proofed poly bags usually have additives within them to help prevent the plastic from becoming brittle, breaking down, or melting &#; all in an effort to keep your food from damage and spoiling.
4. Sustainable Poly Bags
As your business has grown, you may have noticed the number of plastic bags you go through on a daily basis. As each food item is sold, another single-use plastic bag leaves the store, possibly leading you to think about your store&#;s impact on the environment.
But food needs proper storage, and many of the sustainable packaging and storage options available aren&#;t within your budget &#; so, what are you to do?
Fortunately, there are some sustainable poly bag solutions available. At A-Pac Manufacturing, we&#;ve recently started offering sustainable, plant-based poly bags. They have all the strength and durability of man-made polymers, but they&#;re recyclable, biodegradable, and reduce fossil fuels by up to 20% &#; and they&#;re completely safe for your food storage needs.
