Loctite is an industry leader with its lineup of premium adhesives and sealants, including a wide range that are suitable for polyethylene plastic. Just one drop: that's all you need to bond plastic surfaces such as polyethylene when you choose Loctite Plastics Bonding System.
Gorilla Tape contains a highly concentrated rubber based adhesive and sticks to most plastics, including polyethylene (PE) and polypropylene (PP). Gorilla Tape does not work on materials with high oil or plasticizer content, such as EPDM rubber or PVC.
Super glue, or cyanoacrylate, is a great choice for everyday repairs and can dry quickly. Super glues designed to be used with polyethylene or polypropylene might also include a primer to prep the plastic. When using an epoxy, you'll have to mix together a resin and a hardener.
Loctite Super Glue All PlasticsIf you want to buy a polypropylene adhesive that can also be used on other plastics, your best option is Loctite Super Glue All Plastics. This super strength adhesive is the best glue for polypropylene, it bonds in just a few seconds and dries transparent.

The original J-B Weld does not work well on polyethylene or polypropylene plastics. Polyethylene is often used for water or gas containers or garden sprayers. Polypropylene is a harder plastic, durable enough for use on some car radiator parts.
The adherence properties of butyl sealants means that they can bond to metals, concrete, glass, wood, ceramics and plastics (polyethylene, etc.).
Polyethylene tape is a type of tape which has a polyethylene backing with a rubber adhesive. This is used for many general purpose applications, including: Sealing. Color coding.
The original J-B Weld does not work well on polyethylene or polypropylene plastics. Polyethylene is often used for water or gas containers or garden sprayers. Polypropylene is a harder plastic, durable enough for use on some car radiator parts.
Epoxy will not bond polyethylene and polypropylene materials. Neither will polysulfide adhesives such as BoatLIFE Life-Calk, or polyurethane adhesives such as 3M 5200 or Sika-flex. Methacrylates are generally the type of adhesive to use to bond these dissimilar plastics.
Plastic is one of the hardest surfaces to bond to but we have found a hot melt glue stick that will bond polyethylene, PVC and PET. This hot melt is commonly used for PE boxes and display units.
Gorilla Glue doesn't work well on plastic. It's an adhesive that works by creating a chemical bond using moisture, allowing it to expand into both surfaces. Since plastic isn't permeable, the glue can't create a strong bond between the plastic and another surface.

TW-Y01 double sided tape consists of flexible nonwoven fabric carrier with pressure sensitive adhesive. The tape can be easily applied to plastics such as polypropylene and rough surfaces of foams as well as metals.

Polyethylene Tape / PE Tape from IPG is most commonly used in building and construction applications, including stucco masking, and in the remediation industry to seal bags and to secure arm/leg openings in protective clothing.
1" x 60 Yd Clear Rubber Adhesive Packaging Tape Polypropylene film has a smooth, uniform thickness. It is resistant to hightemperatures and most solvents. Packaging tape is used for sealing, splicing, bundling and tabbing in packaging and shipping applications. It In Stock.
An example would be 3M Scotch-Weld DP 8005 Structural Plastic Adhesive. Its two-part structural formulation effectively bonds low surface energy plastics such as polyethylene and polypropylene with other materials, without pre-treating the surface.
According to the manufacturer, Gorilla Glue can work well with many types of plastics, but it's not recommended for use with polypropylene or polyethylene plastics, or with rubber that has a high oil or plasticizer content.
To do this, you can use a good tarp tape, tarp glue (which works only on vinyl tarps, not the more common polyethylene ones), or you can use a soldering gun or plastic welder to "glue" two tarps together by fusing the plastic they're made of.
Silicone has a mediocre shelf life. Butyl tape is easily removed from hard surfaces without damaging the surface, even after years in the application and the same roll of butyl tape will last for years and years on the shelf. Butyl tape also has some drawbacks and applications where it shouldn't be used.
Butyl Seal Tape is permanently flexible, never ages, or dries out.
Bonding polyethylene is extremely difficult because it is a relatively non-stick surface. To glue polyethylene materials, you need a glue made especially for HDPE and LDPE. Polypropylene is also a low surface energy plastic, and is used in food storage and other types of containers because it repels liquids easily.
Single-sided polyester (PET) adhesive tapes comprise a polyester film backing and an adhesive which may be rubber, acrylic or silicone. Polyester adhesive tapes are suited to various applications which require minimal thickness, high tensile strength, and resistance to ageing and temperature.
According to the manufacturer, Gorilla Glue can work well with many types of plastics, but it's not recommended for use with polypropylene or polyethylene plastics, or with rubber that has a high oil or plasticizer content.
For example, I use ≥90.00 as the transition from a B+ to an A-. This means that if your numerical grade is 89.9, I map it to a B+ and not an A-....Why I don't round grades.Number → Letter ConversionNumerical GradeLetter GradeEquivalent on 4.0 scale≥ 92.5A> 3.7≥ 90.0A-> 3.3≥ 87.5B+> 3.0
In conclusion, you can wear sterling silver every day, but you must do so carefully. Regular wear prevents premature tarnishing ONLY if you avoid wearing it when participating in certain activities. Remember: avoid moisture, open-air, and chemicals if at all possible.
Generally (and this varies from district to district in the USA) 90–92 is an A-:, 93–96= A, 97–100+ is an A+.
