Our kraft paper dunnage bag is a professional economical packaging solution specially designed for container transportation cargo gap filling and cargo stabilization. Manufactured with mature transportation packaging technology, this air bag effectively solves common logistics problems such as cargo shaking shifting collision and extrusion damage during long-distance sea land and railway transportation.
The product adopts high-density thickened kraft paper outer layer which features wear resistance tear resistance and strong surface toughness. The inner layer is made of upgraded PA PE multi-layer composite membrane with excellent air tightness pressure resistance and stretch performance It can maintain stable internal pressure for a long time and will not leak air or deform during long voyage and complex road transportation.
This kraft paper inflatable bag complies with international AAR L1 grade standards with stable working pressure below 0.20 bar and maximum burst pressure up to 0.6 bar It is perfectly suitable for gap filling buffering and fixing of light-duty and medium-duty goods in logistics transportation greatly reducing cargo breakage rate.
We support rich standard size specifications covering 5001000mm to 12002400mm All irregular sizes and special customized sizes can be produced according to customer cargo gaps container types and transportation demands to achieve fully fitted packaging.
Equipped with two practical inflation valve options conventional 10mm valve is cost-effective for small-batch manual operation 30mm high-speed ProAir valve greatly improves inflation efficiency with three times faster inflation speed which is very suitable for large-scale factory batch packaging and fast container loading work.
All products implement strict multi-process quality control including raw material screening inner film air tightness test finished product sampling inspection and burst pressure test for each batch Every product is qualified before delivery with stable quality high safety factor and long service life.
Custom printing service is available to print enterprise LOGO shipping warning signs batch traceable codes and company information The unique traceable coding system realizes full-process production traceability facilitating quality control and brand promotion.
The product has passed authoritative SGS MSDS and RoHS certification with non-toxic harmless odorless and pollution-free materials It is fully recyclable and eco-friendly conforming to international green logistics and environmental protection standards.
We provide complete supporting inflation tools including pneumatic inflation guns and portable rechargeable electric inflators helping customers improve loading efficiency save labor costs and shorten container packing cycle.
