Industry Value and Technology Core of stretching film slitter rewinder
Stretching film slitter rewinder is an indispensable and efficient processing equipment in the packaging industry, which is mainly used to slit the wide raw film into narrow rolls to meet the end-use requirements of logistics, food, and electronics industries. According to the Global Packaging Machinery Market Report, the market size of this equipment is expected to exceed $3.2 billion in 2025, with Asia-Pacific accounting for over 45%.
Its core value lies in reducing raw material waste and improving yield through precise slitting and tension control. For example, a head supplier's equipment can control the slitting accuracy to ±0.05mm, saving film costs by 12%-18% per year.
