PLASTICS can be joined with many of the same fasteners that are used to join wood and metal together. Avoid overtightening fasteners — apply torque only until resistance is felt — and use wide washers under bolt or screw heads and nuts to distribute the pressure beyond the fastener.
How do you attach polyethylene to a greenhouse?
It should be taut but not so tight that it has the potential to rip on a cooler day. Pull the polyethylene film over your greenhouse structure until it is even on both sides.

How do you fasten without screws?
Folding and adding bending tabs is one of the easiest and most economical way of making moderately strong joints in sheet-metal parts that will permanently or semi-permanently attach to one another. It requires no screws, rivets, or other pieces of fastening hardware. There are few limitations on fastening tabs.

Push the two pieces of plastic together and hold them there while you run the soldering iron tip along the seam until the two pieces of plastic are partially melted together.
What is the best screw to use in plastic?
Thread-forming screws, generally, function best in thermoplastic materials. Thread-forming screws produce no waste as the plastic that is displaced to create the thread flows back into the root of the thread resulting in a very secure fit. ecosyn®-plast is a great option for a thread-forming screw for plastic.
What kind of screws go into plastic?
Round shank, coarse spiral threads, and blunt tip facilitate use in plastics such as polypropylene and non ferrous castings. These plastic screws have reduced tip for easy entry. Also called thread forming screws, these are commonly used in both soft and hard plastics.

What are corrugated fasteners?
: a small corrugated strip of steel sharp on one of the long edges and hammered in as a fastener across wood joints in rough carpentry.
What are integral fasteners?
