What size bag do I need? – Return to Top
Correctly sizing a bag for your product is a crucial step in the packaging process. To determine the size of the bag, you must first accurately measure the product. Be sure to factor in all dimensions including weight, length and height.
Once you know the size of the product, you must allow for excess room when figuring the size of the bag. While excess is frequently calculated at 1″ – 4″, there is no standard amount of excess. Each product may require a different amount depending on factors including the amount of material for the closure style or the filling process (ie: automated or manual). The style of bag also impacts the amount of excess.

|Bag Width & Length used for a rectangular product:|
|Bag Width =||W + L + Excess|
|4 + 6 + Excess|
|Bag Length =||L + H + Excess|
|6 + 8 + Excess|
(usually 1”-2” on the side and up to 4” at the top)
|Bag Width &Length used for a cylindrical product:|
|Bag Width =||(3.14 X D) /2 + Excess|
|(3.14 x 7) /2 + Excess|
|Bag Length =||D + H + Excess|
|7 + 8 + Excess|
What bag strength/Gauge do I need? – Return to Top
Polyethylene thickness is measured in thousandths of an inch or “mil” thickness. We have the capability to manufacture polyethylene from 0.75mil to 9mil.
Selecting the proper gauge for your packaging can be a complex process. There are many factors to consider including, but not limited to; intended use, strength, overall appearance, environmental impact, cost and much more.
This chart is a general guideline to selecting the proper gauge for your product. However, there are many other factors to consider when choosing your poly bags and film. Call us and we’ll be happy to help you determine the correct mil thickness for your poly bag or film.
What film types and additives are available? – Return to Top
All of our film is made from FDA/ USDA approved resin in an eco friendly environment compliant with AQMD standards. Selecting the proper film type or additive for your packaging can be a complex process depending on the use and type of product packaged. You can use the reference tool below or call us and we’ll be happy to help you through the process.
Polyethylene Film Applications:
Retail consumer product packaging must aesthetically present the product and provide the customer enough information to make an informed decision at the point of purchase. Product packaging for retail often requires poly with high clarity, high gloss and excellent heat seal ability. Low density polyethylene is commonly used to manufacture this type of poly bag. ASTM D2457is the test method used by the ASTM (American Society of Testing Materials) used to test the raw materials for gloss levels.
Food & Bakery packaging used in the United States requires polyethylene from raw materials that comply with the specifications contained in the U.S. Food & Drug Administration (FDA) regulation 21 CFR 177.1520 for olefin polymers. Low Density Polyethylene and Linear Low Density Polyethylene are combined to achieve appropriate levels of protection from moisture and oxygen transfer. ASTM F1249 is the method used to test the Water Vapor Transfer Rate (WVTR), or, in this case, the grams of moisture that pass through one square inch of polyethylene film in a 24-hour period. ASTM F3985 is the method used to test the Oxygen Transfer Rate (OTR), or, in this case, the cubic centimeters of moisture that pass through one square inch of polyethylene film in a 24-hour period.
Frozen Applications require a polyethylene film that can withstand freezing temperatures. Cold Crack is the freezing temperature at which the integrity of the film is compromised.
Poly bags used to package frozen products like ice also require excellent seal strength and puncture resistance. Dart Drop impact measures the resistance of the film to impact. The stronger the film, the higher the dart drop impact. ASTM D1709A measures the dart drop impact.
Medical Supply and Equipment Packaging is used to protect products and equipment from dust moisture and other contaminants. Raw materials used for medical packaging is often required to meet specifications contained in the U.S. Food & Drug Administration (FDA) regulation 21 CFR 177.1520 for olefin polymers. Puncture strength and sealability are often crucial for this application. Medical devices are typically manufactured in a sterile environment. The bags and film surrounding these products must be free of punctures and remain sealed to maintain the sterile environment.
Industrial Packaging is used for heavy industrial applications including transportation of goods, lining containers or covering products. Strength is the most important feature of this film. Strength is measured in many ways depending on the approach. Tensile Yield measures the ability of the film to return to its original shape after being stretched. Tensile Break measures the amount of stress the film can hold before breaking. Tear Strength measures the protection against being torn apart. Puncture resistance measures the protection against contents poking through the bag.
Anti Block – Added to prevent material from sticking together. Often used in hi speed packaging applications
Anti Stat – Takes the natural static out of the bag. Most often used for electrical applications
Slip – Added to make the material less tacky
Are your bags and film FDA/USDA Approved? – Return to Top
Yes. All of our film is made from FDA/ USDA approved resin in an eco friendly environment compliant with AQMD standards.
Are your bags/film DEHP (Phthalate) free? – Return to Top
We use only the highest grade virgin raw materials and do not add DEHP (Phthalates) during our manufacturing process.
Are your bags and film recyclable? – Return to Top
Yes. Keeping the environment clean is a top priority of ours. All of our products are 100% recyclable and produced in an eco friendly environment compliant with AQMD standards.
Is your company “Green”/Eco-Friendly? – Return to Top
Yes! Keeping the environment clean is a top priority of ours. All of our products are 100% recyclable and produced in an eco-friendly environment compliant with AQMD standards.
We keep a tight reign on our production facility assuring that little to no scrap is produced during our manufacturing process.
We are proud to be a part of an industry that helps the environment. The raw materials used to produce plastic bags are derived from ethane, a waste product in the oil and gas refining process. Ethane is repurposed and converted into polyethylene. If ethane were not repurposed into polyethylene, it would be burned off resulting in greenhouse gas emissions.
Additionally, the production of plastic bags compared to other packaging options is much more efficient (up to 70%).
