you need to add the global $post inside of your function. Most of the code examples provided in the documents assume you’re working directly in a template file where WP has declared this global for you. Inside a function you need to do it yourself.

add_action( 'woocommerce_product_thumbnails', 'packagelogos', 20 );
function packagelogos() { 

global $post;

?>
<div class="channel-list">
<?php
$posts = get_field('select');
if( $posts ): ?>
    <?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) ?>
        <?php setup_postdata($post); ?>
			<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
				<div class="channel-list-item">
					<img class="image img-responsive lazyloaded" alt="<?php the_title(); ?>" src="<?php if ( has_post_thumbnail() ) { the_post_thumbnail_url(); } ?>">
					<div class="title"><?php the_title(); ?></div>
				</div>
			</a>
    <?php endforeach; ?>
    <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>									
</div>
<?php
};
