VNK's welcomes RFQs for red line and slider zipper bags

VNK’s is now accepting requests for quotation for two zipper bag styles: red line press-to-close bags and bags with a slider closure. Both can be opened and closed again, giving importers and distributors different options when sourcing custom zipper bags.

Red line zipper bags have a clear, flat body with a coloured closure near the opening. Slider zipper bags have a small slider that travels along the zipper to open and close the bag. Customers can submit an existing sample or specifications for a new design for VNK’s to review and quote.

1. Red line zipper bags: Clear film with a press-to-close seal

Red line zipper bags have a rectangular body and a distinctive red zipper running across the top. The transparent film keeps the contents visible without opening the bag, making items easier to identify and sort.

The closure consists of two interlocking profiles that join when pressed together across the opening. To open the bag, the user pulls the two sides apart. To close it, the user presses along the zipper from one end to the other. Film above the zipper provides an edge to grip. There is no slider or pull tab.

This style suits buyers looking for a conventional press-to-close bag with a recognisable red closure. Its flat body, horizontal zipper and manual closing action distinguish it from a slider zipper bag.

VNK’s accepts RFQs based on the required dimensions, material, thickness and quantity. For orders covering several sizes, customers can submit each specification in one list for the sales team to review.

2. Slider zipper bags: Opening and closing with a sliding fastener

Slider zipper bags have a small sliding fastener on the zipper at the bag opening. Instead of pressing the two profiles together by hand along their length, the user moves the slider to open or close the bag.

VNK’s featured slider bag has a translucent white, rectangular body and a white closure. The slider runs along the horizontal zipper above the product compartment. The opening allows items to be placed inside or removed, then closed again using the slider.

For customers looking for a bag with a sliding closure, this is the key identifying feature. It distinguishes the design from a press-to-close bag, although both belong to the reclosable bag category.

VNK’s welcomes enquiries for custom slider zipper bags from importers and distributors. Customers can provide a reference sample together with their dimensions, thickness and required quantity to discuss an order tailored to their needs.

3. Zipper and bag construction

The zipper is extruded separately and then heat-sealed to the bag film. It sits near the opening, with the bag body below forming the product compartment. Press-to-close and slider closures provide two different ways to operate the opening.

When selecting dimensions, the usable space below the zipper determines whether the contents will fit. Overall bag height also includes the zipper area and the film above it. Two bags with the same external height may therefore have different usable space if their zipper positions differ.

For orders that need to retain an existing bag’s usable dimensions, VNK’s can review photographs or a physical sample to discuss zipper position and measurement points. This helps establish the correct specification, particularly when customers are seeking a new manufacturing source for an existing design.

4. OEM manufacturing for importers and distributors

VNK’s is a plastic bag manufacturer in Vietnam with nearly 20 years of experience, supporting OEM and custom manufacturing for B2B customers.

For zipper bag orders, dimensions, thickness, material, colour, printing and packing requirements are reviewed for each project. Customers can start with an existing bag sample or a specification for a new product.

On HDPE and LDPE bags, VNK’s can provide flexographic printing with up to 12 colours and two-sided printing. Logos, printed content and artwork are reviewed alongside the material and bag construction to determine the production approach.

VNK’s can also handle complex bag structures and multi-step production requirements. Importers can work directly with the sales team to clarify order specifications, while distributors can submit requirements for individual product codes within the range they are sourcing.
