Single-row composite derivative packaging roll special electronic packaging cover tape

Abstract

This invention provides a dedicated electronic packaging cover tape for use with a single-row composite packaging reel. It has a multi-layer composite structure, comprising, in sequence from top to bottom, a light-transmitting substrate layer, an adhesive layer, and a localized (regional) pressure-sensitive adhesive layer. The light-transmitting substrate layer is transparent and heat-resistant; the adhesive layer is stacked on one lower surface of the light-transmitting substrate layer; and the pressure-sensitive adhesive layer is partially stacked and / or arranged on one lower surface of the adhesive layer. The pressure-sensitive adhesive layer has a lateral spacing and / or a longitudinal spacing, the range of which is set to 0.5~50mm to match the pocket size of a single-row composite packaging reel, and the lateral spacing and / or the longitudinal spacing is smaller than the pocket size of the single-row composite packaging reel. After heat sealing or pressing, this invention can form an independent sealing area on the packaging reel, effectively preventing electronic components from slipping or being mixed, and also providing the technical effects of anti-static properties, stable packaging, and reduced material costs.

Claims

1. A single-row, multi-layer composite packaging roll cover for electronic packaging, comprising: A translucent substrate layer, possessing both light transmittance and heat resistance; An adhesive layer is stacked on one of the lower surfaces of the light-transmitting substrate layer; And a pressure-sensitive adhesive layer, partially stacked and / or arranged on one of the lower surfaces of the adhesive layer; wherein the pressure-sensitive adhesive layer has a lateral spacing and / or a longitudinal spacing, the lateral spacing and / or the longitudinal spacing being set to a range of 0.5~50mm to match the pocket size of a single-row composite derivative packaging roll, and the lateral spacing and / or the longitudinal spacing being smaller than the pocket size of the single-row composite derivative packaging roll, so that the pressure-sensitive adhesive layer is arranged in a strip or dot pattern at intervals, and is used to form an independent sealing area between each pocket of the single-row composite derivative packaging roll.

2. The electronic packaging cover strip according to claim 1, wherein, The thickness of the light-transmitting substrate layer is set to 10~50μm, and the light-transmitting substrate layer includes a plastic film material, which includes at least one of PET, PP, PE, PET / PE or PET / PP.
