'EVOLOR Plastic Tape is made in a LEVOLOR factory, on LEVOLOR equipment under LEVOLOR quality controlled supervision. The process is more expensive because it utilizes a proven plastic fabric for a core and then impregnates it with plastic until it is integrated with these plastic fibres. This gives two-way strength. Crossways and lengthwise. Stick it full of holes if you wish, it can't be ripped in either direction. Levolor Plastic tape has an additional overall finish to match the popular Linen Fresh, it really looks like a fabric — not oil cloth.
