Let's talk about adhesive tape that is touted to stick to plastic sheeting (polyethylene sheeting) that is commonly used in various industrial applications. The tape is designed to adhere to a variety of substrates, including metals, plastics, and other materials. However, in some cases, the tape may not stick well to polyethylene surfaces. There are several reasons why this could happen:

1. Low surface energy: Polyethylene has a relatively low surface energy, which means that it can be difficult for adhesives to bond to it. This can make it challenging for some tapes to adhere to polyethylene surfaces.

2. Surface contamination: If the surface of the polyethylene is contaminated with oils, dirt, or other substances, this can interfere with the ability of the tape adhesive to bond to the surface. Even small amounts of contamination can prevent the adhesive from forming a strong bond.

3. Incompatible adhesive chemistry: Certain fire retardant  tape are designed to work with a range of substrates, but it may not be compatible with all types of polyethylene. If the tape adhesive chemistry is not compatible with the particular type of polyethylene used, it may not adhere well to the surface. When slip or other processing aids are used, they make the surface of the polyethylene more slippery, so it slides through the manufacturing equipment more easily, and can be run much faster.  But it remains on the surface on a microscopic level, and makes it more difficult for tape to adhere well. By nature, the surface of the polyethylene is smooth and slippery, so many tapes do not adhere well, even when no processing aids are used.  

4. Temperature and humidity: The environment in which the tape is applied can also affect its ability to bond to polyethylene. If the temperature or humidity is too high or too low, this can interfere with the curing process of the adhesive, which can prevent it from forming a strong bond. The temperature of the tape when applied also affects the adhesion level. Tape should be applied at room temperature if possible.  The cooler the temperature, the lower the adhesion.  How smooth the finish is for each production run varies depending on temperature and humidity in our manufacturing facility. The smoother the finish,  the harder it is for the tape to adhere.

5. Pressure during Installation: Tape is pressure sensitive.  The more pressure used during installation, the higher the adhesion.  And the adhesion increases as the adhesive wets out on the surfaces being bonded.  The higher the initial pressure, the better the final bond.
   
   
6. Density Range:  The polyethylene has a density range.  At the lowest end of the range it is less smooth than at the highest end of the range. This varies with every batch of resin, and every production run.
   
   
7. The Solution: To improve the adhesion of certain tapes to polyethylene surfaces, it may be necessary to prepare the surface by cleaning it thoroughly and using a primer or other surface treatment to increase its surface energy. Additionally, selecting a different tape formulation or adhesive chemistry may be necessary if the tape is not compatible with the particular type of polyethylene being used.

As you can see, a number of factors may come into play as to why a tape is not sticking to polyethylene plastic sheeting.

The Cons of Utilizing HDPE:

It is high flammability, sensitivity to stress cracking, inability to be biodegradable, inability to be composted, lack of resistance to oxidizing acids, lack of resistance to chlorinated hydrocarbons, and its high thermal expansion.

The advantages of using HDPE are as follows:

HDPE has many advantages, such as being cost-effective, able to withstand temperatures ranging from -148 to 176 degrees Fahrenheit, non-leaching, UV-resistant, dishwasher safe, resistant to most chemical solvents, and a stiff material.

Common Uses of High Density Polyethylene of HDPE

High-density polyethylene or HDPE is a commonly used petroleum thermoplastic and the most used of the three polyethylenes for a wide range of applications. If you look at this plastic under a microscope, you would see that it has a linear structure with few branches lending to its optimal strength/density ratio. As a result of its molecular makeup, this polymer shines brightest in applications where moisture resistance and cost-effectiveness are needed.

HDPE was created in the 1930s.  It was introduced to the market commercially soon after. While its higher density versions yield a more rigid result, HDPE can vary in flexibility. Low-density grades of the thermoplastic are less stiff and the high-density grades have equally high crystallinity. HDPE is a versatile thermoplastic that is widely used in a variety of applications. It is known for its durability, cost-effectiveness, and moisture resistance due to its linear structure with few branches. It was first introduced commercially in the 1930s, following its use in high-frequency radar cables during World War II. HDPE can vary in flexibility, with low-density grades being less stiff and high-density grades exhibiting high crystallinity.

Uses for HDPE:

HDPE (High Density Polyethylene) has a variety of common uses. Water bottles are a common introduction to the durable plastic, as its blow-molding properties make it perfect for food and beverage containers. Not only is it recyclable, but it is also UV-resistant, making it ideal for toys. HDPE is also great for chemical containers, such as laundry, shampoo, conditioner, motor oil, antifreeze, and recycling bins. For piping and outdoor applications, HDPE pipe grade sheet is used due to its increased molecular weight and UV-resistance, as well as its ability to withstand temperatures from -220 to 180 degrees Fahrenheit. This makes it ideal for many industrial applications.

If you have ever seen plastic sheeting burn, it goes up in flames and doesn't stop until it's completed its mission.

Let's define "fireproof" as the ablility to withstand fire or great heat.

Fireproof, flame resistant and fire retardant are often interchanged to mean the same thing.

Is there a plastic that is fireproof? 

Plastic in its natural state is not fireproof but it is possible to make plastic that is fireproof.  The secret is incorporating hydrated magnesium oxide or aluminum oxide, as well as phosphorus or bromine compounds, into low-density polyethylene. When exposed to fire, the compounds break down and absorb the heat energy, thus preventing the plastic from burning. The plastic doesnt burn, it melts. 

Watch the video HERE and see a side by side comparison of fire retardant/ fireproof plastic sheeting versus regular plastic sheeting.

PROVE IT! Some if not most states  require commercial establishments to comply with the use of fire retardant plastic sheeting for their events such as amusement parks, schools, haunted houses and so on. Global Plastic Sheeting issues product certification from independent fire testing labs for their fire retardant products. When the fire marshall shows up you will have the necessary documentation for your plastic sheeting.

What is reinforced ployehtylene and what are the benefits?

Reinforced plastic sheeting is manufactured by laminating layers of high-strength polyethylene with a heavy-duty scrim reinforcement between them. This creates a strong film that is highly resistant to tearing and is more durable than construction-grade poly.

The benefits of reinforced poly sheeting include increased strength and durability, improved tear resistance, greater UV protection, and improved resistance to punctures and other environmental hazards. It also offers superior puncture and tear resistance, making it a great choice such as construction enclosures, temporary containment, abatement covers, ground covers, and underlayment.. Additionally, reinforced poly sheeting is often more affordable than other materials, making it a cost-effective alternative.

What is Polypropylene?

Polypropylene while being a plastic polymer shouldn't be confused with polyethylene. Polypropylene is more versatile than polyethylene because it is has a higher melting point (320 degrees Fahrenheit) than polyethylene which melts at 212 degrees Fahrenheit. Additionally it can be produced in a variety of structures which suits the building and construction industry very well.  Polypropylene is used to make rope, indoor-outdoor carpeting and drainage mats.

The fibers are tough and can stand up to weight and won't crush
